Published: September 2022

AbstractObjectivesMental health professionals are becoming increasingly involved in the process of employment rehabilitation of persons with psychiatric disabilities. However, few studies address the attitudes of these professionals toward the employability of those with mental illness. The aim of this research was to identify differences in the attitudes of medical and non‐medical mental health professionals, as well as to detect any association between attitude scores and the type of professional.MethodsA sample of 140 employees from public and third sector mental health organizations answered a questionnaire using a scale measuring their attitudes and views on the employability of people with psychiatric disabilities. The psychometric characteristics of the scale are provided together with the variations detected in the professionals’ attitudes.ResultsThis research shows that significant differences in the attitudes between medical and non‐medical mental health employees exist and that there is a need for the implementation of educational programs that may help to improve the attitudes of medical professionals toward the employability of people with mental illness.ConclusionThis research indicates the importance of improving the professionals’ attitudes to support people attempting to return to work.
Indicators and countermeasures of modern slavery in global supply chains: Pathway to a social supply chain management framework
Authors: Bodendorf Frank , Wonn Fabian , Simon Kristin , Franke Jörg 
Published: September 2022

AbstractEven though global supply chains are (usually unintentionally) tied to slave labor, research and practice have largely ignored the issue. This is expected to change as civil society activism and new legislation increase the risk of litigation and reputational damage to supply chain partners. To deal with and combat modern slavery in the supply chain, a theory inspired social supply chain management framework consisting of indicators and countermeasures of modern slavery in the supply chain is developed. The framework is refined in a qualitative expert interview study. The theoretical framework is then evaluated by a multimethod empirical analysis that includes a multicase study based on publicly available supply chain data from 6000 media articles and company websites as well as a quantitative empirical study based on survey data from 280 corporate sustainability experts operating in global supply networks. The results show that economic, political‐legal, social, and environmental factors have a significant impact on contemporary slavery in the supply chain. The study also motivates supply chain partners to use preventative and detective measures to reduce the probability of encountering modern slavery actions in their supply chain. Theoretical and managerial implications are drawn from the findings, pointing to a holistic approach to combatting modern slavery in the supply chain.
‘It's like a much deeper understanding and you kind of believe them more …’: The value of peer support for young people affected by sexual violence
Authors: Cody Claire , Bovarnick Silvie , Peace Delphine 
Published: September 2022

AbstractResearch demonstrates that relationships are key when working to support young people affected by sexual violence. Within these relationships, young people show a preference for non‐judgemental, flexible, consistent and informal support. Peer support – defined here as support provided by those with similar experiences – is however an uncharted area for assisting young people affected by sexual violence. This paper draws on interviews with 25 respondents with knowledge and experience of setting up, supervising and/or participating in peer support initiatives for young people impacted by different forms of sexual violence in Europe and North America. The article highlights how one form of peer support, peer or ‘survivor’ mentoring, can provide emotional and social support; create space for ‘normality’; and give choices to young people. It outlines three unique dimensions to the support provided by peers more generally: relatability, credibility and translatability. The discussion reflects on what this might mean for traditional support provided by professionals. It also draws attention to the significance of recognising both the variety of experience and identity of young survivors of sexual trauma and the impact this may have on promoting relatability within relationships.
Immobilization of 2‐Deoxy‐d–ribose‐5‐phosphate Aldolase on Membrane Supports by Spray‐Coating: Optimization by Design‐of‐Experiment

Published: September 2022

AbstractA strategy for the immobilization of the enzyme 2‐deoxy‐d‐ribose‐5‐phosphate aldolase (DERA) is presented via spray‐coating on membrane support material to generate an enzymatically active membrane which can be used in continuously run synthesis modules. A functional, water‐soluble copolymer containing addressable units to covalently bind DERA is mixed with the enzyme, followed by spray‐coating of the mixture onto polyacrylonitrile/polyethylene imine‐ (PAN/PEI) membranes and a subsequent post‐processing to stabilize the coating. Confirmation of successful immobilization was achieved by atomic force microscopy (AFM) imaging and assessment of retained enzyme activity. Through variation of relevant parameters, improvements in stability and activity were seen, which formed the basis for the following optimization by Design‐of‐Experiment (DoE). A first fractional factorial design yielded additional performance improvements and important insights into the impacts of experimental parameters and their interaction. A second full factorial design did not result in further improvements, but validated the results of the first design.
Anchoring 0D CeO2 Nanoparticles on 2D LaTiO2N Nanosheets for Efficient Visible‐Light‐Driven Photocatalytic CO2 Reduction

Published: September 2022

AbstractThe efficiency of photocatalytic reduction of CO2 with water to hydrocarbons is largely limited by high recombination rate of photogenerated electrons and holes in the photocatalysts. Herein, 0D/2D CeO2/LaTiO2N S‐scheme heterojunction photocatalyst prepared by simple in‐situ hydrothermal approach realizes the overall conversion of gaseous CO2 and H2O without any sacrificial reagent and cocatalyst. The yields of CH4 and CO over CeO2/LaTiO2N sample under visible light for 3 h are 1.5 and 7.2 μmol g−1, and the corresponding utilized photoelectron number (UPN) is 26.4 μmol g−1, about 7.3 and 7.8 times that of individual LaTiO2N and CeO2, respectively. The enhanced photocatalytic activity of 0D/2D CeO2/LaTiO2N is attributed to the constitution of the S‐scheme heterojunction, which effectively inhibits the recombination of photogenerated carriers. This study is expected to provide a new insight into the construction of efficient 0D/2D photocatalysts for visible‐light‐driven photocatalytic CO2 reduction.
Seismic Stability from Low Ductility to Enhanced Resilience
Authors: Fahnestock Larry 
Published: September 2022

AbstractThe fundamental basis for seismic stability is clear – during an earthquake, a building must be capable of carrying gravity loads while developing large inelastic deformations and associated lateral displacements. However, structural design to achieve this performance objective is complex and depends upon multiple system parameters. In current seismic provisions, the global destabilizing effects of gravity are typically considered with simplistic models that may not properly address the actual inelastic stability response of building structures. Building systems with high ductility are used extensively in high‐seismic regions, but in moderate‐seismic regions, systems with low ductility are ubiquitous. The inelastic responses of low‐ductility and high‐ductility systems are starkly different, and life safety must be ensured across this wide variation in behavior. This paper will discuss foundational seismic stability principles and explore the range of inelastic response that is associated with conventional seismic systems and novel next‐generation systems. Results from large‐scale component tests, full‐scale frame tests and numerical earthquake simulations will be used to demonstrate several important concepts: (1) high‐ductility response is an insufficient, and not always necessary, condition for seismic stability; (2) the most critical parameter for seismic stability is persistent secondary stiffness; (3) emerging technologies like recentering, which limit damage, are promising solutions for enhanced seismic resilience.

Published: September 2022

AbstractRecent disruptive technological advances, including wire arc additive manufacturing (WAAM) and the concept of digital twins, have the potential to fundamentally transform the way in which we design, build and manage structures. WAAM is a method of metal 3D printing that is well suited to the price‐sensitive construction industry and has been used to manufacture the MX3D bridge – the world's first metal 3D printed bridge. The intricate geometry, undulating surface finish and particular material properties rendered the bridge outside the scope of any existing structural design standards; hence, physical testing and advanced numerical modelling were carried out for its safety assessment. The key features of the finite element model of the bridge, and its validation against in‐situ structural tests, are described herein. Subsequent numerical studies undertaken to verify the structural performance of the bridge under various loading scenarios are presented, while the basis for the development of the smart digital twin of the bridge is also introduced. The presented research provides insight into the use of advanced computational simulations for the verification and ongoing assessment of structures produced using new methods of manufacture.
Properties of Structural Steels in Historical Railway Bridges by Diagnostic Tests
Authors: Hołowaty Janusz , Wichtowski Bernard 
Published: September 2022

AbstractOver their long service life, steel bridge structures are subjected to functional and material degradations. As a result, these bridges require periodical investigation and assessment of their current resistance. This should be done according to the recommendations of the European Convention for Constructional Steelwork (ECCS), in force since 2008. The paper presents the technical condition of 13 steel bridges built between 1873 and 1890 and 17 bridges from the years 1907 to 1983. The age division given above is prescribed by the great changes in technology and materials which appeared at the turn of the 20th century, the development of structural steel and the appearance of modern higher strength steels in bridge constructions. The mechanical properties of the steels and their chemical compositions are given. The steel test results and conclusions may be useful for others investigating historic steel bridges.

Published: September 2022

AbstractStanding seam panels are offering un‐competed metal roofing solution with respect to water leakage prevention. Therefore, need to develop new Standing Seam profiles and alternative seaming techniques is rising now a days. However, standing seam panels wind uplift capacities have no specification or closed form equations and tests are usually needed in order to evaluate clip and seaming capacities. Testing an assembly of the standing seam panels in air chamber equipped with adequate air bumps is usually done for this purpose. However, same types of lab equipment are not available in many developing countries and shipping assemblies overseas for testing is costly. Consequently, developing testing method that is economic and fairly accurate is needed. In this study, standing seam clip connection is designed and tested separately in universal testing machine. The designed details are simulated numerically using nonlinear finite element model. Cladding sheets are modeled using hybrid shell & solid elements while connecting fasteners are modeled using beam elements, Results of the developed testing techniques are compared with that of large scale standing roof system tested using air bump chamber. Failure loads of the isolated clip connection are compared with that in the large scale panels failure modes.
Yield‐line Mechanisms of Endplate Connections with Eight Bolts and Circular Bolt Configurations Using DLO
Authors: Timmers Ralph , Lang Robert 
Published: September 2022

AbstractDesigning bolted endplate connections is a typical problem in practice. Nevertheless, the calculation of such endplates is not that easy. Due to the deformation of the plate, the resultant prying forces influence the resistance of the connection. The so‐called T‐stub model considers prying effects and is included in the EN 1993‐1‐8 for typical endplates with two bolts and rectangular bolt configurations. It was found in the literature that circular bolt configurations can have some benefits compared to rectangular ones, like a better stress distribution in the plate and bolts, resulting in higher resistances. Systematic research on the evolution of the yield‐line mechanisms is still not available, which is the focus of the presented study. We investigated and compared the yield‐line mechanisms and ultimate loads of typical rectangular and circular bolt configurations. A parameter study has been worked out by varying the endplate thickness for each case. The calculations were made with the Discontinuity Layout Optimization (DLO) concept, directly offering the kinematic mechanisms and corresponding ultimate loads. Finally, we gave some simple recommendations for calculating the ultimate loads of circular bolt configurations.

Published: September 2022

AbstractIn the framework of a recent RFCS project, innovative joint solutions named FREEDAM were developed with the objective of proposing beam‐to‐column joints able to dissipate the seismic energy with limited or even no damages. The efficiency of the proposed solutions was validated through experimental, numerical, and analytical investigations on moment resisting frames (MRFs) and dual concentrically braced frames (D‐CBFs). However, according to modern design codes, including the Eurocodes, structures subjected to accidental events such as impact, explosion, or loss of a bearing element should not undergo damages disproportionate to the initiating cause. Accordingly, to validate the proposed solutions, it was also required to demonstrate the ability of structures equipped with FREEDAM joints to exhibit an appropriate level of robustness in case of such accidental events. This paper presents the robustness assessment performed on 20 MRFs and D‐CBFs. The loss of a supporting column was considered in full agreement with the Eurocode requirements. Analytical and numerical studies are conducted to demonstrate how the request for robustness influences the design of the joints which were initially tailored for seismic performances.
Influence of Strain‐hardening on the Load‐carrying Behaviour of Bearing Type Bolted Connections
Authors: Studer Patrick , Taras Andreas 
Published: September 2022

AbstractThe investigations presented in this conference paper focus on the hole bearing resistance of symmetric single‐bolt connections, taking into account the distinct hardening behaviour of various steel grades and quantifying its impact on the resulting load‐carrying behaviour. They synthetize the findings of a larger study that was published in full in previous publications by the authors. The main focus of the study was put on the limitation of the hole bearing deformations by defining a corresponding “resistance”, which is thus a quantity with the background of an implicit deformation limitation.Experimental investigations were carried out on four different steel grades, each with eight different geometries, in order to investigate the influence of this hardening behaviour on the hole bearing deformations. The paper presents a new approach to define the point on the load‐deformation curve between acceptable and excessive deformations. Based on the results of the hole bearing tests in combination with the new approach to define the transition point between acceptable and excessive deformations, an adapted resistance model is presented. In this model, the hardening behaviour of the steel is taken into account, whereby here specifically the ratio fu/fy of tensile strength to yield strength influences the load‐bearing behaviour.The proposed adaptation of the hole bearing verification which takes the fu/fy ratio into account facilitates the optimal use of material and can thus save resources. The format of the hole bearing verification remains almost unchanged, which should simplify its applicability in practice.
Buckling Resistance of Longitudinally Stiffened Panels with Closed Stiffeners under Direct Longitudinal Stresses
Authors: Pourostad Vahid , Kuhlmann Ulrike 
Published: September 2022

AbstractThe buckling behaviour of panels may be determined according to EN 1993‐1‐5 [1]. Most of the design rules relating to stiffened panels in EN 1993‐1‐5 were derived on the basis of open‐section stiffeners. Several recent investigations have shown that the application of the design rules according to EN 1993‐1‐5 [1] taking into account the torsional stiffness of the stiffeners may overestimate the resistance of the panels. Therefore, the recent Amendment A2 to EN 1993‐1‐5 states that the torsional stiffness of stiffeners should generally be neglected in determining critical plate buckling stresses. In addition, prEN 1993‐1‐5 [2] provides rules for considering the torsional stiffness of stiffeners. However, in this paper it will be shown that even the rules of prEN 1993‐1‐5 are not reliable as far as torsional stiffness is concerned. The paper focuses on the investigation of the buckling behaviour of stiffened panels with closed section stiffeners subjected to constant longitudinal compression stresses and shows improved rules to consider the torsional stiffness of the stiffeners. For this purpose, a new interpolation equation between column‐like and plate‐like behaviour is proposed, based on an extensive numerical parametric study. The proposal provides a safe and economic solution, as it considers the torsional stiffness of stiffeners when applying the rules of prEN1993‐1‐5.
Elastic Lateral‐Torsional Buckling of Girders with Corrugated Web: Equivalent Section Properties Approach
Authors: Fernandez‐Lacabe David , Lopez Claudio , Serna Miguel Angel 
Published: September 2022

AbstractOne of the benefits of using corrugated web girders is the increase of lateral‐torsional buckling resistance. Different approaches have been presented to obtain the value of the critical moment as a function of the cross‐section geometry. Previous research works consider that the increase in buckling resistance must be accredited to a higher warping constant. The paper presents a systematic finite element numerical analysis of girders with different corrugated web shapes. Bending with respect to the weak axis shows that corrugated web implies higher moment of inertia. Torsion analysis results clearly demonstrate that the increase of torsion resistance is mainly due to higher torsional constant. The paper compares the elastic critical moment values obtained by using finite element elastic buckling analysis with the values provided by theoretical expressions introducing equivalent section properties. Results show that the equivalent section properties approach provides values very close to those obtained using finite elements. Finally, the paper presents closed form expressions to directly compute approximate equivalent section properties of any girder with corrugated web, which compare very satisfactory with those values obtained with finite element buckling analysis.
Distortional‐Global Interactive Failure and DSM Design of CFS Lipped Channel Columns at Elevated Temperatures
Authors: Filho Elisson Bilheiro Ferreira , Landesmann Alexandre , Camotim Dinar 
Published: September 2022

AbstractThis work addresses the behavior and DSM‐based design of cold‐formed steel lipped channel fixed‐ended columns failing in distortional‐global (flexural‐torsional) modes at elevated temperatures. It extends the scope of previous studies, carried out in the context of columns at room temperature, by considering columns under elevated temperatures (up to 800° C), due to fire conditions, with various cross‐section dimensions and lengths, selected so that they undergo different levels of distortional‐global (flexural‐torsional) (D‐FT) interaction. The results presented and discussed consist of post‐buckling equilibrium paths, failure loads and collapse modes of lipped channel columns affected by D‐FT interaction, and are obtained through Abaqus shell finite element geometrically and materially non‐linear analyses. The model prescribed in EC3‐1.2 is used to describe the temperature‐dependence of the cold‐formed steel material properties and, in order to cover a wide D‐FT slenderness range, several room‐temperature yield stresses are considered. The numerical failure loads obtained are used (i) to assess the merits of existing DSM‐based design approaches and also, if necessary, (ii) to propose modifications aimed at achieving an efficient failure load prediction for lipped channel columns undergoing D‐FT interaction at elevated temperatures. A few design considerations are drawn from the findings reported in this work, which provide encouragement to extend the current research activity to columns with other cross‐section shapes and/or support conditions, thus leading to a safe, economic and reliable DSM‐based design approach for CFS columns failing in D‐FT interactive modes at elevated temperatures.
A Global Convergent Method for Strength Capacity Evaluation of Composite Sections Subjected to Fire
Authors: Chiorean Cosmin G 
Published: September 2022

AbstractThe paper presents a new advanced computational method for ultimate and nominal strength analysis of composite steel‐concrete cross‐sections with arbitrary shape subjected to elevated temperatures. The capacity diagrams are evaluated for a given bending‐moments ratio, generating plane and smooth distribution points on interaction diagrams. The ultimate (maximum) strength capacity is formulated as a problem of constrained mathematical optimization of the total bending moment, whereas the proposed approach evaluates the nominal strength capacity by means of enforcing the nonlinear equilibrium equations in conjunction with a total strain field tangent at the ultimate strain surface. Both methods are unified within the same strain‐driven algorithm used to solve the resulted nonlinear coupled equations. This algorithm coupled with a bracketing approach by means of combining Bisection and Newton method represents the main computational framework to ensure global convergence of the developed methods. An adaptive effective plastic centroid has been introduced ensuring that the origin of the reference axes is within the iso‐load contour circumventing in this way any potential convergence issues. The computational examples prove the effectiveness and the reliability of the proposed method.
