The application of black-box modeling in long-term tunnel deformation monitoring
Authors: Maes Kristof , François Stijn , Salens Wim , Feremans Gerrit , Segher Koen
Published: October 2021

Tunnel closures related to maintenance and reconstruction works can lead to large economical costs and should therefore be avoided. This paper explores the use of novelty detection algorithms for long-term tunnel monitoring. The aim is to detect tunnel damage in an early stage, as such providing a tool to support the asset management. The proposed strategy is applied to the monitoring of the Waasland tunnel in Antwerp, where the deformations and temperatures have been monitored over a period of 14 months. The case demonstrates that novelty detection by means of principal component analysis enables the identification of minor changes in the tunnel response, and can therefore be embedded in an early detection warning system.

Published: October 2021

Composite bridges with encased steel beams, or nowadays, rather encased steel continuous shear connectors are a welcome option for short span railway or road bridges. With lower construction height and easy construction of prefabricated composite beams it brings a new, complex, solution for replacement of older, overserved bridges, as well as for new tasks. At Technical University of Košice, Faculty of Civil Engineering a new designed of the steel perforated strip was developed. At Laboratory of Excellent Research several experiments for resistance finding were carried together with material tests. In this article the numerical analysis of push-out tests performed is closely described and the shear resistance of finite element model developed in Abaqus/CAE is compared to experimental results.

Authors: Gens Frédéric , Comeliau Ludivine
Published: October 2021

The newest footbridge in Liège, known as "La Belle Liégeoise", was opened on 2nd May 2016. Located upstream of the landscape window created by Guillemins esplanade, this bridge provides a connection for soft transport modes from the railway station across the Meuse to La Boverie park, maintaining clearance for navigation.

The main span over the Meuse is 163 metres for a total length of 294 metres. The 5.5 metre wide decking is positioned laterally to the supporting structure.

Bureau Greisch, in association with the landscape architect Corajoud, was responsible for the complete design mission for the bridge.

The aim of this article is to detail the whole process of the conception of the bridge, from first sketches to erection control.
Impact of the structural model used on the steel hall fire resistance assessment
Authors: Maslak Mariusz , Pazdanowski Michal , Suchodola Maciej
Published: October 2021

It is presented in detail how the selection of a structural model describing steel hall frame in a more or less complex way may affect fire resistance evaluation for such hall. In the examples compiled in this paper the same typical one-aisle and single-story steel hall is subjected to simulated fire action, each time following the same fire development scenario. A resultant fire resistance is identified individually in each case, using various computational models, on an appropriate static equilibrium path obtained numerically. It is shown that the greater the simplification of the model used, the more overstated the estimated fire resistance is in relation to its real value. Such an overestimation seems to be dangerous to the user, as it gives him an illusory but formally unjustified sense of the guaranteed safety level.
Application of viscous dampers for structural response reduction in building renovation
Authors: Daohang Hu , Xin Zhao
Published: October 2021

This paper introduces a new idea in the reconstruction and continuation projects. By arranging damping devices, the additional damping of the structure is increased, thereby reducing the dynamic response of the structure under the new seismic precautionary criterion. This paper focuses on the study of viscous dampers which one of the damping device, introduces the energy dissipation principle of viscous dampers, and combines a two-story plane frame case to analyze and compare the dynamic response between non-damping structure and damping structure. The location and quantity of the arrangement were compared with multiple models. Through analysis, it can be seen that by equipping with viscous dampers, seismic energy can be effectively dissipated, thereby reducing the workload of structural reinforcement and having less impact on the original structure. Finally, two commonly analysis methods in damping structures are studied, direct integration method and fast nonlinear analysis (FNA), the main differences between the two analysis methods are introduced, and the calculation results of the two methods are compared and analyzed.

One major issue when considering the effects of climate change is to understand, qualify and quantify how natural hazards and the changing climate will likely impact infrastructure assets and services as it strongly depends on current and future climate variability, location, asset design life, function and condition. So far, there is no well-defined and agreed performance indicator that isolates the effects of climate change for structures. Rather, one can mention some key considerations on how climate change may produce changes of vulnerability due to physical and chemical actions affecting structural durability or changes of the exposure in terms of intensity/frequency of extreme events. This paper considers these two aspects and associated challenges, considering some recent activities of members of the IABSE TG6.1.
Longitudinal response of a cable-stayed bridge to wind loads using fluid-structure interaction simulations
Authors: Sánchez-García Raúl , Gómez-Martínez Roberto
Published: October 2021

Cable-stayed bridges are highly susceptible to wind effects, both in the construction and service phases, due to their high flexibility, low damping, and the geometric shape of the deck and pylons. Their study, under the effect of the wind, is complicated if they are built-in mountainous regions since the winds can be subject to complex flow patterns (the wind speed is not constant in time and space). Normally, scale models are subjected to different tests in wind tunnels. However, with the improvement, in recent years, of the capacity of computers and the development of computational fluid dynamics algorithms, it has been possible to investigate the flow patterns of wind around civil structures prototypes. This paper presents the study of a long cable-stayed bridge through fluid- structure interaction (FSI) simulations to estimate its longitudinal structural response. The numerical model considers the topography of the bridge construction site. The response obtained is compared with the results of an aeroelastic model of the complete bridge in a wind tunnel
Investigations on the structural behaviour of CFRP reinforced concrete members for modular bridge constructions
Authors: Bosbach Sven , Knorrek Christian , Hegger Josef , Stark Alexander
Published: October 2021

The requirements for existing bridge structures increased significantly in the last years because of increasing traffic volume and higher total vehicle weights. Strengthening of existing bridges as well as necessary reconstructions are expensive, often complex and strongly influence traffic. Hence, the development of new methods for sustainable bridge constructions with short erection periods becomes a macroeconomic issue. Modular bridge constructions made of precast concrete elements with reinforcement systems made of corrosion-resistant carbon fibre reinforced polymer (CFRP) represent a particularly suitable solution for these demands. Modular systems are reasonable to realise short construction times and the application of durable CFRP reinforcement ensures a longer lifetime of the bridge. This paper reports on a developed concept for a modular system made of prefabricated concrete elements with CFRP reinforcement and on tests investigating the structural behaviour of prestressed CFRP reinforced concrete members.
Timber and concrete hybrid superstructures – a potential step towards sustainability?
Authors: Sleiman Martin , Johansson Mikael , Claesson Anders
Published: October 2021

Timber is a renewable material having a lower carbon-footprint than conventional concrete and steel. Hence, timber would be a good choice of material to minimize the carbon-footprint of a building. Superstructures of pure timber are, however, cumbersome to use for multistory purposes

– timber is simply too light to stabilize the building properly. Hence, the interest in timber and concrete/steel hybrid structures is increasing. The purpose of this paper is to investigate the potential savings of CO2 emissions in the design of a multistory residential building - this by using timber and concrete in its superstructure instead of only concrete and concurrently ensuring global stability. The study is performed on an existing 17-story residential building with a pure concrete superstructure: The results indicate that the carbon-footprint of the building in question could have been reduced by 48% if a hybrid superstructure had been used instead.
Using movable modular grandstands in large sports stadia
Authors: Van Staen Gilles , Outtier Amelie , De Backer Hans
Published: October 2021

The King Baudouin Stadium in Brussels is for many years the national stadium for football and athletics of Belgium. Being built in 1930 and renovated in 1995, one can image the stadium is outdated and not conform the current safety regulation. Since building a completely new stadium brought too many complexities with it, the latest idea is to renovate the current stadium. A major point of attention is the fan experience in the stadium, which is hard to achieve during football games when a running track is around the pitch. Therefore, a hybrid stadium with modular seats is suggested. It allows to modify the stadium in an ideal way for each event. Two different systems are worked out to move the stands, due to structural and financial considerations. One is based on the use of air cushions, while the other system makes use of cantilever beams. For both systems, it is important to protect the running track, when the stands are in football mode. This modular system creates a lot of extra space in the stadium and will enhance the atmosphere in the arena according to each type of event.
Repair project of a vehicular bridge damaged during the 2017 Puebla- Morelos earthquake: seismic evaluation
Authors: Cervantes David , Guerrero Héctor , Escobar J. Alberto , Gomez Roberto
Published: October 2021

This paper shows the results of nonlinear analyses, static and dynamic, conducted on a vehicular bridge located in Mexico City. The main characteristics of the developed numerical model and the results of the analysis, in terms of capacity curves, global and by element, are presented. Two repair cases were studied. The first one considers seismic restrainers, located at the bridge abutments, which can effectively limit the lateral movements. The second case considers reduced lateral restriction. The results show that the former case provides an adequate safety factor for the bridge, while the latter resulted in a marginal safety factor.
Finite element analyses of a buckling-restrained pile
Authors: Mashayekh Adel , Handzhiyski Lachezar , Harris Stephen K.
Published: October 2021

In existing building renovation projects, the strength of the structure is often limited by the capacity of existing foundations. Foundation strengthening typically consists of expanding existing footings and/or adding piles to supplement load-carrying capacity. These traditional methods are generally not feasible for the retrofit of mat foundations where increasing the mat footprint is unlikely to reduce bearing pressure considerably and adding piles outside the mat will change the distribution of internal stresses and may affect the long-term differential settlement behaviour of the structure.

This paper presents finite element analyses that were performed as part of the development of a new approach to retrofitting mat foundations which consists of enlarging the footprint of the existing mat and adding piles that include an innovative axial capacity-limiting mechanism. The maximum resistance provided by these piles to the existing foundation can be tuned to not exceed the maximum connection capacity that can be achieved at the interface between the existing mat and the new mat extension. The proposed design is unique in that the pile axial load is limited even under significant potential settlements experienced by the rest of the building foundation.
FEM based approach for development of a new high-speed load model for railway bridges
Authors: Vorwagner Alois , Kwapisz Maciej , Flesch Rainer , Kohl Antonia M. , Firus Andrei , Vospernig Michael , Arana Villafán Tomás
Published: October 2021

The high-speed load model (HSLM), developed more than 20 years ago, is defined in the code "EN 1991-2" for a dynamic analysis of railway bridges - with respect to ballast destabilisation - within lines with a vehicle speed of more than 120 km/h. The compliance with the (dynamic) load bearing capacity and the serviceability acceleration must be verified for designing new bridges and assessing existing bridges, especially if a speed increase on the railroad is intended. New vehicle types, which are not always covered by the standardised load model, must be examined additionally. This leads to a clear and an urgent need for a revision of the existing high-speed load model. Within this paper, a large-scale dynamic FEM computation including 17 million train passages is presented as a basis for developing a new standard-compliant dynamic load model within the ongoing international project, commissioned by the German EBA (Federal Railway Authority).
Wind response sensitivities of a long suspension bridge
Authors: Svendsen Martin N.
Published: October 2021

The sensitivities of wind-induced design section forces in the main girder of a suspension bridge with a span greater than 1000m are determined under variation of 20 different wind response calculation parameters. The investigated parameters cover turbulence characteristics such as length scales and correlation decay constants, as well as aerodynamic properties of the structure including both static coefficients and aerodynamic derivatives. The response calculations are performed considering both fully correlated static mean wind effects as well as low-frequent quasi-static and resonant turbulence effects. The study further comprises a detailed assessment of the convergence of stresses in the main girder as a function of number of included eigenmodes. Additionally, a full multi-modal response calculation including aeroelastic coupling effects is performed to quantify the accuracy of the simpler mode-by-mode calculation method.

Authors: Ding Luchuan , Van Coile Ruben , Botte Wouter , Caspeele Robby
Published: October 2021

The alternative load path (ALP) method is widely used to investigate the performance of reinforced concrete (RC) buildings in case of progressive collapse (or disproportional collapse) scenarios. This kind of analysis can be carried out either in a static way or in a dynamic way. In this contribution, these methods are compared by means of nonlinear static and nonlinear dynamic analysis methods. A 5-storey RC frame subjected to two different sudden column removal scenarios is adopted as a case study. The probabilistic analysis considers 12 random variables. On the basis of the stochastic results, a dynamic amplification factor (DAF) is calculated. The mean values of the DAF are 1.114 and 1.102 for the external column removal scenario (Case A) and the internal column removal scenario (Case B), respectively. Compared to the failure probabilities obtained through a static analysis, the failure probabilities for the incremental dynamic analysis results are 184.0% and 180.7% higher for Case A and Case B, respectively.

Published: October 2021

The Response Surface Method (RSM) has become an essential tool to solve structural reliability problems due to its accuracy, efficacy, and facility for coupling with Nonlinear Finite Element Analysis (NLFEA). In this paper, some strategies to improve the RSM efficacy without compromising its accuracy are tested. Initially, each strategy is implemented to assess the safety level of a highly nonlinear explicit limit state function. The strategy with the best results is then identified and used to carry out a reliability analysis of a prestressed concrete bridge, considering the nonlinear material behavior through NLFEA simulation. The calculated value of 𝛽 is compared with the target value established in Eurocode for ULS. The results showed how RSM can be a practical methodology and how the improvements presented can reduce the computational cost of a traditional RSM giving a good alternative to simulation methods such as Monte Carlo.
Optioneering of long viaducts via parametric design
Authors: Sobota Paul M.
Published: October 2021

During the optioneering phase, engineers face the challenge of choosing between myriads of possible designs, while, simultaneously, several sorts of constraints have to be considered. We show in a case study of a 380 m long viaduct how parametric modelling can facilitate the design process. The main challenge was to satisfy the constraints imposed by several different stakeholders. In order to identify sustainable, aesthetic, economic as well as structurally efficient options, we assessed several key performance indicators in real time. By automatically estimating steel and concrete volumes, a simple, yet suitable approximation of the embodied carbon (considering 85-95%) can be obtained at a very early design stage. In summary, our parametric approach allowed us to consider a wider range of parameters and to react more flexibly to changing conditions during the project.

Barus is an area where most of the people are fishermen, this is because Barus is an area located on the coast. The existing condition shows the shoreline on the east side of the seawall building, the condition of the shoreline is experiencing abrasion resulting in the retreat of the coastline and almost reaches the fisherman's flat building area, this is due to the port building in the form of a massive trester jutting into the sea resulting in sediment supply to the retained flat towers and the coastline has declined.To maintain the stability of the coastline, it is necessary to make an effort to control the damage to water in this area. The shoreline model is a numerical forecast model based on the sediment continuity equation and the sediment transport rate equation along the coast. Sediment transport rates along the coast are a function of the variation in height and direction of waves along the coast formed by the effects of refraction and diffraction.

The results of the shoreline change model with the protection of the fisherman's flat area from waves by building sea walls is the east side of the fisherman's towers abrasion ± 7 m and sedimentation ± 5 m, the front area of the fisherman's towers does not occur sedimentation or abrasion, the western side of the fisherman's towers does not sedimentation and abrasion occurred, the east side of Barus Jetty did not occur abrasion or sedimentation, the area of Barus Jetty occurred ± 20 m sedimentation, and the west side of Barus Jetty occurred sedimentation ± 9 m. These results indicate that for handling conditions by making a seawall in front of the flat area shows that the location is safe from scouring of waves

Published: October 2021

The city is an important center of social life. In different historical periods of time, the role of cities was changing, as well as the city image in the picture of the world and in the society system of values. The study of the city image is one of the urgent tasks of urban studies, as well as the entire humanitarian knowledge with the involvement of various historical sources. The article sets out a task of studying the city image using the example of textbooks for teaching literacy (Primers) as books that form the initial picture of the human world. To that end Karion Istomin’s illustrated Primer was chosen. It was first created in handwritten form to teach the children of Tsar Alexei Mikhailovich. In 1694 it was published at the Moscow Printing Yard. Boards for that all-engraved edition were made by the engraver Leonty Bunin. A Рrimer is a combination of verbal and visual information. For the first time in it an important feature became the illustrative series was important, which was supposed to help the student in mastering letters of the alphabet. Each page of the Primer consisted of pictures with captions and a poem. They interpreted words that began with or included the letter being studied. Among the illustrations by Leonty Bunin, images of the city and city buildings occupy a significant place. As a result of the study of verbal and visual information about the city and the urban environment, the following images of the city are distinguished in the article: the city as a sacred space; the image of a city as a geographical marker (depicting parts of the world through the creation of different types of cities);image of city’s architecture (buildings for the residence of townspeople, churches, outbuildings, protective and the fortification structures); the city image as a symbol of the native land. It was important for the formation of a picture of the world among youths starting to learn to read and write. Through the visual-verbal series of the image of the city, children formed a certain perception of the urban environment, urban space – different and multifunctional.
THE FLAG OF THE SHIP “EAGLE/ORYOL” IN THE CONTEXT OF THE FORMATION OF RUSSIAN STATE SYMBOLS
Authors:   Russian State University for the Humanities, Pchelov Evgeniy V.
Published: October 2021

The article considers the issue of designing the flag for the first Russian ship “Eagle/Oryol”, built by decree of Tsar Alexey Mikhailovich from 1667. The designing of that flag is in the context of the formation of new state symbols and visual representation of power at the end of the War with the Polish-Lithuanian Commonwealth. It took place in the late 1660s and early 1670s. At the period, a new version of the state coat of arms, a new coat of arms banner, and then new versions of the title coats of arms were created. An image of a double-headed eagle on the ship “Eagle” ensign (warship flag), perceived as the national flag of Russia, was the most important identifying feature of the ship’s ensign. The color scheme of the flag was not so important and it was determined in 1668. It consisted of three colors – red, white and blue. In historiography, the opinion took hold that the above first Russian flag consisted of four parts formed by a straight cross. However, such a version is not sufficiently confirmed by sources. On the contrary, it can be assumed that the flag of the ship “Eagle” was similar to the Dutch one. Whether they managed to sew the image of a double-headed eagle on its cloth is an open question.
“BULYGINSKAYA DUMA”. AGENCY WITHOUT POWER OR POWER OF AGENCY?

Published: October 2021

The article considers the attitude of representatives of the top bureaucracy to the draft of the State Duma, developed by a Special Council chaired by the Minister of the Interior A.G. Bulygin in 1905. Particular attention is paid to the high officials assessments of the dignitaries of the place and role of the Duma in the system of state administration of the Russian Empire, the arguments that officials cited in favor of its convocation. It analyzes intellectual context of the emergence of the “bulyginskaya duma” (“Bulygin Duma”) project is analyzed, which largely determined the breadth of the actual, not declared powers of the people’s agency. The research is based on unpublished documents from the funds of state institutions, as well as materials from the personal funds of officials and public figures. The article shows that, despite the legislative nature of the Duma, it had to have significant powers. The electoral system, which was proposed and defended by the high officials, was originally modeled in such a way as to avoid the triumph of the estates principle. The monarch’s open opposition to the people’s agency was considered a politically short-sighted move, which indicated a limitation of his power. The results of the study allow considering the government policy in 1905 not as an untimely response to public demands, but as a conscious strategy for systemic political reforms.

Published: October 2021

Mold flux entrapment during continuous casting of steel contributes to both surface and sub-surface defects in the final product. Continuous casting operating parameters such as casting speed, SEN immersion depth, SEN port geometry, argon flow, and mold EMS significantly affect the mold flow conditions and flow profile. During continuous casting operation, SEN immersion depth is continuously varied to avoid localized erosion of SEN, and it impacts the flow dynamics in the mold. In the present work, water modeling studies were carried out for a wide range of mold widths (1200-1800 mm) and casting speeds (0.8-1.4 m/min) on a 0.5 scaled down water model to optimize casting speed for different combinations of SEN immersion depth and mold width. Results from water modeling were further validated using nail board studies in the actual plant. A safe operating matrix was identified from these experiments to avoid mold slag entrapment during continuous casting.

Published: October 2021

This study examines the accumulation of metallic mercury by several types of plants in the traditional gold processing area in the village of Gogore, Buru district. The plants that were sampled in this study were guava, lempuyang gajah, and harendong bulu. These three plant species were chosen because they dominate the vegetation in the gold processing area. The analysis results showed that the lempuyang gajah was the plant that accumulated the highest mercury metal, namely in the roots of 16.79 ppm and the leaves of 15.03 ppm. Guava plants accumulated metal mercury in the roots and leaves of 11.73 ppm and 9.90 ppm, respectively. Meanwhile, harendong plants accumulated mercury in the roots and leaves of 2.59 ppm and 10.39 ppm, respectively. The BCF values ​​of guava, lempuyang gajah, and harendong bulu plants were 1.58, 0.41, and 0.39, respectively. Meanwhile, the TF values ​​of the three plants were 0.84, 0.89, and 4.01, respectively. From these results, it can be concluded that the three plants can accumulate mercury in high enough concentrations, so these three types of plants are categorized as hyper tolerant plants and accumulators.

The article presents the findings of seismic hazard zoning of the submerged crossing of the pipeline in the Nevelskoy Strait, between the village Lazarev of the Nikolaevsky district, Khabarovsky Krai, and the Cape Pogibi near the Pogibi village, Sakhalin Oblast. Along the water area, this section of the submerged crossing is limited by the zone which is 500 m wide by 11 km long. It follows from the stock of geological documents of the Geophysical Service of the Russian Academy of Sciences and the OSP-2015 map that the highest seismic activity in the Okhotsk region is observed in the area of the Kuril Islands, and the central seismically prone zone of northern Sakhalin is closest to the construction site. Large earthquakes are recorded by a number of seismological stations in the immediate vicinity of the construction site. The foci of nearby earthquakes occur east of the construction site and are mostly confined to the systems of deep faults resulting from the juncture between the West Sakhalin synclinorium and the Sikhote-Alin volcanic belt. The main purpose of the research is related to the development of a methodology for prognosticating seismic effects for the strong earthquake prone areas. In this context, an approach is proposed for the specific structure, which is based on the construction of a set of seismic models to reach the reference bedrock, setting of the pickup signal corresponding to the initial seismicity of the area, calculating the main parameters of seismic effects for them, and then, in a first approximation, the implementation of the technology for constructing engineering-seismological cross-section along the pipeline construction site. The proposed approaches to prognosticating seismic events for that part of the pipeline submerged crossing in the Nevelskoy Strait are based on certain constraints that made it possible to obtain a set of parameters of seismic effects for prognosticated strong earthquakes necessary for designing and constructing an earthquake-resistant linear structure. Given improved calculation methods and critical object monitoring, the advantage of this approach is the ability to recalculate seismic effects to the structure using the constructed seismic ground motion models.

Predmet je rada kontradiktornost pravila parničnog postupka za dosuđivanje troškova u slučaju djelomičnoga povlačenja tužbe. Do utvrđivanja kontradiktornosti dolazi se analizom pravila za odlučivanje o troškovima
parničnog postupka u slučaju djelomičnog povlačenja tužbe i pravila za dosuđivanje troškova u slučaju djelomičnog uspjeha u parnici. Na hipotetičko postavljenom primjeru ukazuje se na razlike do koji se dolazi primjenom tih pravila. Na temelju pravila za tumačenje prava lex specialis derogat legi generali i lex posterior derogat legi priori, dolazi se do zaključka da kod djelomičnog povlačenja tužbe treba primijeniti pravila za dosuđivanje troškova parničnog postupka u slučaju djelomičnog uspjeha.
Ustavna pismenost kao preduvjet građanske pismenosti

U povodu 30. godišnjice donošenja Ustava RH (22.12.1990. – 22.12.2020.) polazimo od teze da je u RH podrazvijena politička kultura koja doprinosi nekvalitetnom djelovanju ustavne demokracije u našoj državi. S obzirom na poznatu poveznicu između građanske i ustavne pismenosti, gdje je druga temeljni sastojak prve, razvili smo opći mjerni okvir ustavne pismenosti i proveli istraživanje ustavne pismenosti najobrazovanijih građana grada Rijeke. Uzorak čini 44 % (N=561) od ukupnog broja nastavnika Sveučilišta u Rijeci, Veleučilišta u Rijeci i Poslovne akademije Rijeka. Analiza rezultata dovodi do sljedećih zaključka. Postoji značajni interes za poznavanje sadržaja, djelovanja i tumačenje našeg Ustava. Postojeće se znanje, međutim, ponajprije zadržava na razini osnova i općih znanja uz vrlo zabrinjavajuće nepoznavanje ustavnih refleksija na svakodnevni život društvene zajednice, kao i recentnu stvarnost. Eklatantni su primjeri sljedeći: preko 46 % ispitanika ne zna kako se formira vlada RH (koja je većina potrebna za osvajanje vlasti), preko 42 % ne zna da je održan referendum o braku i 70 % ispitanika ne zna da pravo EU-a ima primat pred pravom svake države članice, pa tako i RH. Istodobno i ohrabrujuće, utvrđena je i odgovarajuća razina samokritičnosti kroz korektnu procjenu vlastitog (ne)poznavanja Ustava RH, kao i relevantna samoinicijativna spremnost na (online) edukacije o toj tematici.
