Best Practice Guide

description: Work Package 7 ‘Application Enabling and Support’ provides applications enabling support for HPC applications codes which are important for European researchers to ensure that these applications can effectively exploit multi-petaflop systems. Applications will be selected either via PRACE Preparatory Access or identified as addressing major socio-economic challenges with the advice of the PRACE Scientific Steering Committee. This applications enabling activity will use the most promising tools, algorithms and standards for optimisation and parallel scaling that have recently been developed through research and experience in PRACE and other projects.
 Through the applications-enabling work, WP7 develops specific expertise on most, if not all, of the architectures which make up the European HPC system. PRACE-1IP provided best practice guides on the PRACE Tier-0 systems that cover programming techniques, compilers, tools and libraries. PRACE-2IP supplemented these with best practice guides for the other architectures which are important at Tier-1 to allow European researchers to make efficient use of these systems. Finally, PRACE-3IP Task 7.3 called ‘Support for European Researchers’ supplements these with best practice guides for current and future HPC systems.
 Topics for these best practice guides include: optimal porting of applications (e.g., choice of numerical libraries and compiler options); architecture specific optimisation and scaling techniques; optimal system environment (e.g. tuneable system parameters, job placement and optimised system libraries); debugging tools, performance analysis tools and programming environment.
 This report describes the process which led to the best practice guides. For the best practice guides itself we refer to the online versions on the PRACE RI web site.
Advanced Computational Fluid Dynamics models for liquid metal flows

Publisher: name: Alma Mater Studiorum - Università di Bologna
Year: 2016
Subjects: ING-IND/19 Impianti nucleari

description: In this thesis it is shown the development, implementation and numerical solution of several computational fluid dynamics models for the study of liquid metal flows. The work is organized in two main parts in which different modeling techniques are analyzed. These two parts are introduced by a brief chapter on the finite element methods and on the  computational platform developed during the Ph.D. studies which have been the basis for the implementation and numerical solution of all the developed mathematical models.
In the first part, turbulence modeling based on Reynolds Averaged Navier Stokes equations is considered for the study of turbulent heat transfer in liquid metal flows. A new four parameter turbulence model is introduced and validated in two different k-e and k-w formulations. Several results in four geometries interesting for the fast nuclear reactor field  are reported in order to assess and prove the feasibility of this model for the study of turbulent heat transfer in liquid metal flows.
In the second part the adjoint optimal control theory is introduced. Some numerical cases are presented by solving the optimality system with state and adjoint variables. The first application is a temperature boundary optimal control in which an improved way of setting boundary conditions in weak form has been developed. The second application is a distributed optimal control problem for the RANS system. Numerical simulations in two and three dimensions have been carried on for this type of applications and are reported in the final chapter.

description: We present the way of calculation of displacement in the bent reinforced concrete bar elements where rearrangement of internal forces and plastic hinge occurred. The described solution is based on prof. Borcz’s mathematical model. It directly takes into consideration the effects connected with the occurrence of plastic hinge, such as for example a crack, by means of a differential equation of axis of the bent reinforced concrete beam. The EN Eurocode 2 makes it possible to consider the influence of plastic hinge on the values of the reinforced concrete structures. This influence can also be assumed using other analytical methods. However, the results obtained by the application of Eurocode 2 are higher from those received in testing. Just comparably big error level occurs when calculations are made by means of Borcz’s method, but in the latter case, the results depend on the assumptions made beforehand. This method makes it possible to apply the experimental results using parameters r1 i r0. When the experimental results are taken into account, one could observe the compatibility between the calculations and actual deflections of the structure.

Subjects: ING-INF/01 Elettronica

description: As human beings, we trust our five senses, that allow us to experience the world and communicate. Since our birth, the amount of data that every day we can acquire is impressive and such a richness reflects the complexity of humankind in arts, technology, etc. The advent of computers and the consequent progress in Data Science and Artificial Intelligence showed how large amounts of data can contain some sort of “intelligence” themselves. Machines learn and create a superimposed layer of reality.
How data generated by humans and machines are related today? To give an answer we will present three projects in the context of “Mixed Reality”, the ideal place where Reality, Virtual Reality and Augmented Reality are increasingly connected as long as data enhance the digital experiences, making them more “real”.
We will start with BRAVO, a tool that exploits the brain activity to improve the user’s learning process in real time by means of a Brain-Computer Interface that acquires EEG data. 
Then we will see AUGMENTED GRAPHICS, a framework for detecting objects in the reality that can be captured easily and inserted in any digital scenario. Based on the moments invariants theory, it looks particularly designed for mobile devices, as it assumes a light concept of object detection and it works without any training set.
As third work, GLOVR, a wearable hand controller that uses inertial sensors to offer directional controls and to recognize gestures, particularly suitable for Virtual Reality applications.  It features a microphone to record voice sequences that then are translated in tasks by means of a natural language web service.
For each project we will summarize the main results and we will trace some future directions of research and development.
A compendium of existing vulnerability and fragility relationships for flood : preliminary results
Creators: name: Pregnolato, Maria

Publisher: name: The University of British Columbia
Year: 2015

description: In the last decade, probabilistic approaches for flood risk assessment have emerged, often as an extension of more consolidated methods used in probabilistic seismic risk assessment. Nonetheless, only a few studies deal with best-practice methodologies for flood vulnerability assessment and existing approaches lack of an appropriate guidance for their selection. These concerns underline the need for a rational, integrated and complete compendium of all the existing flood-related vulnerability and fragility relationships to be used in a comprehensive probabilistic flood risk assessment framework. Following the same approach used in the guidelines recently developed by the Global Earthquake Model (GEM) Project, this paper presents a preliminary review of the state-of-art regarding existing empirical vulnerability and fragility curves in the context of flood risk. In particular, a worldwide overview is intended in terms of data sources, assets features and also statistical techniques employed for data collection and fitting. The research aims at providing a complete and flexible guide for selection of vulnerability and fragility curves for building structures. A discussion on data sources, building classification and considered features, and damage scales is presented, in order to evaluate the reliability, and at the same time the limitations, of different approaches and provide recommendation for future studies.
Coordination Issues in Complex Socio-technical Systems: Self-organisation of Knowledge in MoK
Creators: name: Mariani, Stefano <1987>
Publisher: name: Alma Mater Studiorum - Università di Bologna
Year: 2016
Subjects: ING-INF/05 Sistemi di elaborazione delle informazioni

description: The thesis proposes the Molecules of Knowledge (MoK) model for self-organisation of knowledge in knowledge-intensive socio-technical systems.
The main contribution is the conception, definition, design, and implementation of the MoK model.
The model is based on a chemical metaphor for self-organising coordination, in which coordination laws are interpreted as artificial chemical reactions ruling evolution of the molecules of knowledge living in the system (the information chunks), indirectly coordinating the users working with them.
In turn, users may implicitly affect system behaviour with their interactions, according to the cognitive theory of behavioural implicit communication, integrated in MoK.
The theory states that any interaction conveys tacit messages that can be suitably interpreted by the coordination model to better support users' workflows.
Design and implementation of the MoK model required two other contributions: conception, design, and tuning of the artificial chemical reactions with custom kinetic rates, playing the role of the coordination laws, and development of an infrastructure supporting situated coordination, both in time, space, and w.r.t. the environment, along with a dedicated coordination language.
First-Order and Buckling Analysis of Thin-Walled Members with Deformable Cross-Section within the Generalized Beam Theory

description: In this work, the Generalized Beam Theory (GBT) is used as the main tool to analyze the mechanics of thin-walled beams. After a brief introduction to the subject, the attention is focused on the constitutive relations both for the isotropic and the orthotropic cases. In particular, a novel approach based on energetic arguments , able to automatically select appropriate constitutive relations in accordance with the GBT kinematics, is presented. Furthermore, the concept of consistency of a GBT-based model is introduced and a consistency analysis is conducted. This provides a formal basis to investigate the effects of various families of cross-section deformation modes in terms of predictive capabilities of the GBT model. Later, a new finite element for GBT beams is presented. The element is based on the hybrid complementary energy functional, involving nodal displacements and equilibrating stresses within the element as indipendent variables. Assumed stresses are rationally derived basing on the stresses associated to analytical solutions of some particular cases. The numerical results show the high performance of the proposed element. Subsequently, in the framework of cold-formed stability verification, a verification approach called Embedded Stability Analysis is shown. The verification approach, based on the GBT, is an interesting alternative to the simplified procedures provided by current standards and it is applicable in a simple and general way. A synthetic parameter allows the designer to evaluate when it is more appropriate to consider the distortional effects in thin-walled stability check. Finally, in the framework of cold-formed stability analysis, a new version of the so-called approach ECBL (Erosion of the Critical Load Bifurcation), based on the GBT, is presented. The numerical results show an excellent agreement between the new version ECBL approach and the experimental results.
Efficient computational models for the optimal representation of correlated regional hazard
Creators: name: Christou, Vasileios
name: Bocchini, Paolo
Publisher: name: The University of British Columbia
Year: 2015

description: In this paper, a methodology is presented for the generation of an optimal set of maps representing the intensity of a natural disaster over a region. In regional hazard and loss analysis, maps like these are commonly used to compute the probability of exceeding certain levels of intensity at all sites, while also providing information on the correlation among the intensity at any pair of sites. The information on the spatial correlation between two locations is of utmost importance for the accurate disaster performance assessment of lifeline components and of distributed systems. However, traditional hazard maps (such as those provided by USGS) do not provide this essential information, but only the probability of exceedance of a specific intensity at the various sites, considered individually. Therefore, many researches have attempted to address this problem and incorporate correlation in their models, mainly with two basic approaches. The first approach includes analytic or computational methodologies to assess directly the correlation; the second approach is adopted by techniques for the selection of a representative set of intensity maps, ofter referred to as “regional hazard-consistent maps”. The methodology presented herein, which branches out from the previous two approaches, considers the intensity maps as random fields. By adopting this abstract perspective, the new methodology is particularly appropriate for a multi-hazard approach, and it can take advantage of tools for the optimal sampling of multi-dimensional stochastic functions. These tools ensure that the weighted ensemble of generated samples (i.e., intensity maps) tends to match all the probabilistic properties of the field, including the correlation. In fact, the samples generated by the proposed methodology fully capture the marginal hazard at each location and the correlated regional hazard. After the technique is presented, an application is provided, for the case of seismic ground motion intensity maps.

description: The changed global security situation in the last eight years has shown the importance of emergency management plans in public buildings. Therefore, the use of computer simulators for surveying fire safety design and evacuation process is increasing. The aim of these simulators is to have more realistic evacuation simulations. The challenge is, firstly, to realize the virtual simulation environment based on geometrical and material boundary conditions, secondly, to considerate the mutual interaction effects between different parameters and, finally, to have a realistic visualization of the simulated results. In order to carry out this task, an especial new software method on a BIM-platform has to be developed which can integrate all required simulations and will be able to have an immersive output BIM ISEE (Immersive Safety Engineering Environment). The new BIM-ISEE will integrate the Fire Dynamics Simulator (FDS) for fire and evacuation simulation in the Autodesk Revit which is a BIM-platform and will represent the simulation results in the immersive virtual environment at the institute (CES-Lab). With BIM-ISEE the fire safety engineer will be able to obtain more realistic visualizations in the immersive environment, to modify his concept more effectively, to evaluate the simulation results more accurately and to visualize the various simulation results. It can also give the rescue staff the opportunity to perform and evaluate emergency evacuation trainings.

description: Es gibt kein Buch der Heiligen Schrift, dessen Verständnis so umstritten ist wie das zur biblischen Weisheitsliteratur gerechnete Buch 'Hohelied' (Hld) aus dem Ersten Testament. Bis zum Beginn der Neuzeit genoss das Buch, in dem es um die erotische Liebe geht, höchste Wertschätzung in Theologie und Frömmigkeit: es galt als eines der wichtigsten Bücher der Heiligen Schrift und wurde in der Regel 'geistig' gedeutet - als Allegorie auf die Liebe Gottes zu den Menschen. Mit der Reformation nun gewinnt der literale Schriftsinn an Bedeutung, nach dem Hld nur noch eine profane Liebesgeschichte zwischen zwei Menschen ist. Die in der Folge einsetztende Entwicklung der historisch-kritischen Exegese und ihre zunehmende Deutungshoheit leiten einen Paradigmenwechsel ein, der nach und nach zu einem fast völligen Bedeutungsverlust von Hld führt: Das bis ins 17. Jhd. hinein am meisten kommentierte Buch ist plötzlich keiner Erwähnung mehr wert, sondern löst im Gegenteil Befremden aus. Das ändert sich erst in jüngerer Zeit, die das Gesamtverständnis der Heiligen Schrift wieder mehr in den Blick nimmt.

Wie ist Hld nun im Kontext einer zeitgenössischen Pastoral zu verstehen? Wie ist es gewinnbringend einzusetzen? Könnte eine Synthese aus beiden Auslegungen die Lösung sein? Diese Arbeit unternimmt den Versuch, exemplarisch an einem Vers aus dem Hohelied (Hld 8, 6-7) Zeitgemäßheit, Sinnhaftigkeit und praktisch-theologische Relevanz einer Synthese der Auslegungsmethoden, wie sie seit dem Vat II gefordert ist, aufzuzeigen und zu belegen, dass es dafür gute systematisch-theologische Gründe gibt, welche die Bibelwissenschaft zudem anschlussfähig macht für den interreligiösen Dialog und das interdiziplinäre Gespräch.

description: ASCE 7-10 introduced new seismic design maps that define risk-targeted ground motions such that buildings designed according to these maps will have 1% chance of collapse in 50 years. These maps were developed by iterative risk calculation, wherein a generic building collapse fragility curve is convolved with the U.S. Geological Survey hazard curve until target risk criteria are met. Recent research shows that this current approach may be unconservative at locations where the tectonic environment is much different than that used to develop the generic fragility curve. This study illustrates how risk-targeted ground motions at selected sites would change if generic building fragility curve and hazard assessment were modified to account for seismic risk from subduction earthquakes and near-fault pulses. The paper also explores the difficulties in implementing these changes.
Medicinal Plants from Ancient Tradition as a Source for Matrix Proteases Inhibitors. Study of Correlation between Biological Activity and Phytochemical Profile

Subjects: BIO/15 Biologia farmaceutica

description: Considering the crucial involvement of matrix metalloproteinases’ (MMPs) misregulated activity in the pathogenesis of several degenerative diseases, this class of enzymes has been considered a highly active set of targets for the design of new therapeutic agents. However, the scant success of synthetic MMP inhibitors, largely due to the disappointing results obtained in both clinical and preclinical studies, makes medicinal plants a valuable source of new active compounds able to modulate MMPs activity. 
In this work, a consistent number of plants, selected on the base of an ethnobotanical research, were tested as inhibitors of collagenase, the founding member of the MMPs family.
1H-NMR-based metabolomic analysis combined with multivariate data treatment (PLS and OPLS) was used to correlate the biological activity to the phytochemical profiles, suggesting tannins as an important class of collagenase inhibitors. Thus, a tannin-removal procedure was developed, which allowed to prove this hypothesis and to identify another class of active metabolites, the glucuronide-conjugated flavonoids (especially quercetin-3-O-β-glucoronide), whose the plant Alchemilla vulgaris was found to be a good source.
In another stage of the project, different varieties of tea were investigated as collagenase inhibitors, finding black tea samples particularly potent.  
Then, an OPLS model was developed with the aim of correlating the biological activity to the UV-Vis spectra of teas, showing that a high activity was related to absorption values in the range 350-440 nm. A subsequent fractionation of the most active tea sample was carried out, and this approach allowed to corroborate the results obtained by the metabolomic analysis. Considering that the absorbance measurement of an extract represents a cheap and simple procedure, the proposed method can be suitable, for instance, to select the best tea variety to be developed as an anti-wrinkles cosmetic or food supplement.

description: Obiettivo: Valutare se l’ecografia eseguita prima dell’applicazione di ventosa ostetrica, in particolare la determinazione ecografica della posizione dell’occipite fetale, migliori l'outcome del parto. Prima valutazione in itinere dei dati raccolti.
Materiale e metodi: Studio randomizzato, in aperto, multicentrico. Le pazienti primigravide con feto singolo, cefalico, a termine di gestazione che necessitano di un parto vaginale operativo sono state randomizzate, previo consenso informato, per essere valutate mediante sola visita ostetrica vs. visita ostetrica ed ecografia sovrapubica per la determinazione della posizione dell’occipite fetale. L’outcome del parto, le complicanze materne e fetali sono state paragonate fra i due bracci di studio.  
Risultati: Da Maggio 2014 a Dicembre 2015 sono state reclutate 91 pazienti, 40 (45%) sono state sottoposte ad ecografia e visita digitale mentre 51 (55%) a sola visita ostetrica. L’età gestazionale al parto è risultata di 39,5 ± 1,2 settimane. 57 pazienti (64,8%) sono state sottoposte ad analgesia epidurale. Le principali caratteristiche cliniche e demografiche sono risultate paragonabili nei due gruppi di studio. 
Conclusioni: Dall’analisi dei primi dati raccolti non emergono differenze statisticamente significative rispetto agli outcome d’interesse. I numeri ancora troppo esigui non consentono, però, di trarre conclusioni definitive.
description: Objective: To evaluate if ultrasound evaluation of fetal occiput position before vacuum extraction improves the delivery outcome. 
Material and methods: Multi-centre randomised trial. Nulliparous women, at term, with single cephalic fetus undergoing vaginal instrumental delivery have been randomized, after written consent, to receive clinical assessment (standard care) or ultrasound evaluation and clinical assessment. The delivery outcome, fetal and maternal complications have been compared between the two groups.  
Results: From May 2014 to December 2015 91 patients have been recruited: 40 (45%) in the ultrasound group and 51 (55%) in the clinical evaluation group. Gestational age at birth was 39,5 ± 1,2 week. 57 patients (64,8%) have been submitted to epidural analgesia.  Mean birth and demographic features were comparable between the two groups. 
Conclusions: Preliminary data show no statistically significant differences between the two groups. Although number are too small to drawn any conclusion.

description: The main aim of the research project in progress is to develop virtual models as tools to support decision-making in the planning of construction maintenance. The virtual models gives the capacity to allow them to transmit, visually and interactively, information related to the physical behaviour of materials, components of given infrastructures, defined as a function of the time variable. The interactive application allows decisions to be made on conception options in the definition of plans for maintenance, conservation or rehabilitation. The first virtual prototype that is now in progress concerns just lamps. It allows the examination of the physical model, visualizing, for each element modelled in 3D and linked to a database, the corresponding technical information concerned with the wear and tear aspects of the material, calculated for that period of time. In addition, the analysis of solutions for repair work or substitution and inherent cost are predicted, the results being obtained interactively and visualized in the virtual environment itself. The aim is that the virtual model should be able to be applied directly over the 3D models of new constructions, in situations of rehabilitation. The practical usage of these models is directed, then, towards supporting decision-making in the conception phase and the planning of maintenance. In further work other components will be analysed and incorporated into the virtual system.

description: The majority of bridge infrastructure in Italy has been built in the 60’s and 70’s without specific seismic provisions. Therefore, it is expected that they reveal high seismic vulnerability if subjected to a significant seismic event. Given this background, it is natural that rapid and accurate assessment of economic losses incurred to bridge infrastructure can play a crucial role in emergency management in the immediate aftermath of an earthquake. Focusing on the infrastructure system of highway bridges in the Campania region, it is shown how state of the art methodologies in portfolio loss assessment and available data can be implemented in order to assess the probability distribution of the repair costs incurred to the portfolio in question due the Irpinia 1980 earthquake. Formulating the probabilistic loss assessment for the portfolio of bridges as a standard Monte Carlo Simulation problem helps in resolving the spatial risk integral efficiently. One of the specific features of this case-study is the use of statistical methods for updating, a) ground motion prediction; b) vulnerability/fragility; and c) exposure/cost models based on available data. It has been observed that alternative hypotheses with regard to the ground motion correlation structure can significantly affect the distribution of the direct economic loss. Furthermore, updating the ground motion prediction based on available recordings may significantly reduce the dispersion in the estimation of the direct economic losses.

description: This deliverable summarises the activities of “Task 4.3: Training Portal” of the Training Work Package (WP4) of the PRACE Third Implementation Phase (PRACE-3IP) project, from July 2012 to December 2013.
 We describe how the PRACE Training Portal has been further developed from the PRACE First and Second Implementation Phase (PRACE-1IP and PRACE-2IP) projects, where it now acts as a central online hub and repository for high quality PRACE training material that are useful for self-learning and teaching purposes. The widespread global use of the portal is a good indicator of the quality of the PRACE Training Portal.
 During PRACE-3IP this task has continued the maintenance and development of the PRACE Training Portal through the addition of training material from PRACE training events and through the creation of video tutorials in relevant areas of HPC that are of interest to both academic and industrial research scientists.
 The integration of Google Analytics to the portal in PRACE-3IP has helped to identify potential collaboration partners within Europe and beyond. These collaborations have been initiated and will continue in the remainder of PRACE-3IP.
 With data from Google Analytics there is evidence that the goal to provide access to high quality training material in HPC for European scientists is being realised by the PRACE Training Portal. The number of visits to the portal has been significantly high, with the majority of visits emanating (but not exclusively) from European countries. Specifically, between May and December 2013 there were close to 5,500 visits to the PRACE Training Portal with close to 3,500 unique visitors.
 The web traffic data collected also shows the global outreach of the PRACE Training Portal, as traffic to the portal originates from many countries outside of Europe, including those that may have not had close interaction with PRACE in the past. A good example of this global appeal is the high volume of traffic originating from South Korea.

description: Quality is one of the most important properties of a product. Providing the optimal quality can reduce costs for rework, scrap, recall or even legal actions while satisfying customers demand for reliability. The aim is to achieve ``built-in'' quality within product development process (PDP). The common approach therefore is the robust design optimization (RDO). It uses stochastic values as constraint and/or objective to obtain a robust and reliable optimal design. In classical approaches the effort required for stochastic analysis multiplies with the complexity of the optimization algorithm. The suggested approach shows that it is possible to reduce this effort enormously by using previously obtained data. Therefore the support point set of an underlying metamodel is filled iteratively during ongoing optimization in regions of interest if this is necessary. In a simple example, it will be shown that this is possible without significant loss of accuracy.

description: The numerical simulation of microstructure models in 3D requires, due to enormous d.o.f., significant resources of memory as well as parallel computational power. Compared to homogeneous materials, the material hetrogeneity on microscale induced by different material phases demand for adequate computational methods for discretization and solution process of the resulting highly nonlinear problem. To enable an efficient/scalable solution process of the linearized equation systems the heterogeneous FE problem will be described by a FETI-DP (Finite Element Tearing and Interconnecting - Dual Primal) discretization. The fundamental FETI-DP equation can be solved by a number of different approaches. In our approach the FETI-DP problem will be reformulated as Saddle Point system, by eliminating the primal and Lagrangian variables. For the reduced Saddle Point system, only defined by interior and dual variables, special Uzawa algorithms can be adapted for iteratively solving the FETI-DP saddle-point equation system (FETI-DP SPE). A conjugate gradient version of the Uzawa algorithm will be shown as well as some numerical tests regarding to FETI-DP discretization of small examples using the presented solution technique. Furthermore the inversion of the interior-dual Schur complement operator can be approximated using different techniques building an adequate preconditioning matrix and therewith leading to substantial gains in computing time efficiency.

description: The uncertainty existing in the construction industry is bigger than in other industries. Consequently, most construction projects do not go totally as planned. The project management plan needs therefore to be adapted repeatedly within the project lifecycle to suit the actual project conditions. Generally, the risks of change in the project management plan are difficult to be identified in advance, especially if these risks are caused by unexpected events such as human errors or changes in the client preferences. The knowledge acquired from different resources is essential to identify the probable deviations as well as to find proper solutions to the faced change risks. Hence, it is necessary to have a knowledge base that contains known solutions for the common exceptional cases that may cause changes in each construction domain. The ongoing research work presented in this paper uses the process modeling technique of Event-driven Process Chains to describe different patterns of structure changes in the schedule networks. This results in several so called “change templates”. Under each template different types of change risk/ response pairs can be categorized and stored in a knowledge base. This knowledge base is described as an ontology model populated with reference construction process data. The implementation of the developed approach can be seen as an iterative scheduling cycle that will be repeated within the project lifecycle as new change risks surface. This can help to check the availability of ready solutions in the knowledge base for the situation at hand. Moreover, if the solution is adopted, CPSP, “Change Project Schedule Plan „a prototype developed for the purpose of this research work, will be used to make the needed structure changes of the schedule network automatically based on the change template. What-If scenarios can be implemented using the CPSP prototype in the planning phase to study the effect of specific situations without endangering the success of the project objectives. Hence, better designed and more maintainable project schedules can be achieved.

description: Simplified modelling of friction grip bolted connections of steel member – to – gusset plate is often applied in engineering practise. The paper deals with the simplification of pre-tensioned bolt model and simplification of load transfer within connection. Influence on normal strain (and thus stress) distribution at critical cross-section is investigated. Laboratory testing of single-angle or double-angle members – to – gusset plates bolted connections were taken as basis for numerical analysis. FE models were created using 1D and 2D elements. Angles and gusset plates were modelled with shell elements. Two methods of modelling of friction grip bolting were considered: bolt-regarding approach with 1D element systems modelling bolts and two variants of bolt-disregarding approach with special constraints over some part of member and gusset plate surfaces in contact: a) constraints over whole area of contact, b) constraints over the area around each bolt shank (“partially tied”). Modelling of friction grip bolted connections using simplified bolt modelling may be effective, especially in the case of analysis concerning elastic range only. In such a case disregarding bolts and replacing them with “partially tied” modelling seems to be more attractive. It is less time-consuming and provides results of similar accuracy in comparison to analysis utilizing simplified bolt modelling.

description: In order to model and simulate collapses of large scale complex structures, a user-friendly and high performance software system is essential. Because a large number of simulation experiments have to be performed, therefore, next to an appropriate simulation model and high performance computing, efficient interactive control and visualization capabilities of model parameters and simulation results are crucial. To this respect, this contribution is concerned with advancements of the software system CADCE (Computer Aided Demolition using Controlled Explosives) that is extended under particular consideration of computational steering concepts. Thereby, focus is placed on problems and solutions for the collapse simulation of real world large scale complex structures. The simulation model applied is based on a multilevel approach embedding finite element models on a local as well as a near field length scale, and multibody models on a global scale. Within the global level simulation, relevant effects of the local and the near field scale, such as fracture and failure processes of the reinforced concrete parts, are approximated by means of tailor-made multibody subsystems. These subsystems employ force elements representing nonlinear material characteristics in terms of force/displacement relationships that, in advance, are determined by finite element analysis. In particular, enhancements concerning the efficiency of the multibody model and improvements of the user interaction are presented that are crucial for the capability of the computational steering. Some scenarios of collapse simulations of real world large scale structures demonstrate the implementation of the above mentioned approaches within the computational steering.

description: Due to increasing numbers of wind energy converters, the accurate assessment of the lifespan of their structural parts and the entire converter system is becoming more and more paramount. Lifespan-oriented design, inspections and remedial maintenance are challenging because of their complex dynamic behavior. Wind energy converters are subjected to stochastic turbulent wind loading causing corresponding stochastic structural response and vibrations associated with an extreme number of stress cycles (up to 109 according to the rotation of the blades). Currently, wind energy converters are constructed for a service life of about 20 years. However, this estimation is more or less made by rule of thumb and not backed by profound scientific analyses or accurate simulations. By contrast, modern structural health monitoring systems allow an improved identification of deteriorations and, thereupon, to drastically advance the lifespan assessment of wind energy converters. In particular, monitoring systems based on artificial intelligence techniques represent a promising approach towards cost-efficient and reliable real-time monitoring. Therefore, an innovative real-time structural health monitoring concept based on software agents is introduced in this contribution. For a short time, this concept is also turned into a real-world monitoring system developed in a DFG joint research project in the authors’ institute at the Ruhr-University Bochum. In this paper, primarily the agent-based development, implementation and application of the monitoring system is addressed, focusing on the real-time monitoring tasks in the deserved detail.
