Abstract Variable cross‐section beams are widely used, especially I‐section stepped beams with variable height, which have benefits such as saving materials to match the moment diagrams, reducing the structure height, and access for technical services. However, lowering the beam height also leads to a significant decrease in lateral torsional buckling resistance. Currently, the standards do not provide calculation rules for this type of beam yet, and some studies on lateral torsional buckling of beams have only focused on those with varying flange width and thickness while keeping the beam height constant. This article introduces an approximate formula to determine the critical moment of simply supported I‐section beams when the height varies. The proposed formula is validated by comparing with finite element simulation results obtained by COMSOL Multiphysics 5.6. The evaluation shows that the formula has a low coefficient of variation and high coefficient of determination, ensuring its reliability.

Abstract The building and construction sector is responsible for approximately 40 % of global carbon emissions, and if improvement is not made in the short term, this impact will probably double in the next 20 years. Recently, the European Green Deal set a target of achieving net‐zero greenhouse gas emissions by 2050, for which the construction industry will need to apply drastic measures given the significance of its impact on the global emissions. Efficient ways of proceeding in that direction, allowing to quantify and effectively reduce the carbon emissions of buildings and infrastructures, rely on life‐cycle assessments (LCA) and circularity concepts. Applying the latter in practice requires a paradigm shift, which is necessary to implement in the earliest stages of a construction project if an effective, robust and realistic result is targeted. This article covers some key principles which can be kept in mind for the preparation of a circular construction project, as well as some pioneering projects in Europe which highlight a real possibility of delivering circular steel buildings.

Abstract Steel and composite structures usually have interfaces to concrete walls or concrete foundations. The design and verification of the interaction between steel and concrete is challenging because the load‐carrying behaviour as well as the different material properties have to be taken into account. Steel‐to‐concrete joints can be realised economically and with comparatively little effort by using fasteners such as headed studs for the anchorage in the concrete. Recent investigations have shown that a holistic verification of joints is possible, if the concrete failure mechanisms are integrated into the concept of the component method of steel and composite structures. This allows an economical verification that is competitive with pure concrete solutions because the load‐carrying behaviour in the concrete is captured with the concrete components and the steel components of the joints do not have to be oversized to avoid failure in the concrete. The load‐carrying capacity of the steel‐to‐concrete joints can effectively be improved by taking into account the reinforcement which allows for a significant increase of the resistance of the concrete components. By arranging the reinforcement in the area of the fasteners, it is possible to achieve a higher load‐carrying capacity and, with a suitable design of the reinforcement, also a ductile behaviour of the joint. In the following article, joints are described that were studied in the dissertation (Ruopp, 2020) and were investigated with regard to the above‐mentioned aspects. The article concludes with an outlook on the normative implementation.

Abstract In large mobile equipment in seismically active regions, seismic stability is often a decisive design criterion, and the behaviour of this large equipment, which is characterised by uplift, tilting and rocking, can only be calculated by means of nonlinear time history analyses. Here, the model damping approach has a significant influence on the results of these analyses but there are no scientific approaches for large mobile equipment with nonlinear behaviour such as uplift. In this paper, possible theoretical damping approaches for nonlinear time history analysis of structures with uplift such as large mobile equipment are discussed and numerical studies are conducted to investigate the influence of damping in the model on the concise results of the typical behaviour of large mobile equipment under seismic excitation. A suitable new approach is to be developed and a way of practical implementation is being prepared. Experimental studies on real typical bucket wheel machines will identify and validate important natural frequencies and associated damping for the numerical approach. These can be applied in numerical models using the damping approach engineered in the theoretical part. Thus, realistic results of the numerical models under nonlinear seismic time history analyses can be expected and more precise conclusions on the distinctive behaviour of large mobile equipment with uplift can be drawn.

Abstract The article presents the current status of the revision of EN 1993‐1‐11 with regard to the design of saddles and clamps for ropes or for parallel wire tension components for suspended structures. The focus here is on presenting a general approach for clamps. For saddles, emphasis is on types where the slip resistance is – in addition to the component from deviation forces – increased by clamping forces, although general aspects are also covered. This part 2 deals with the geometrical requirements for clamps and in particular saddles and with the associated verification of the transverse pressure. Finally, testing is briefly discussed, with the emphasis on linking the design and the confirmation of the assumptions made thereby with the tests.

Structural health monitoring is the process of implementing a continuous damage detection strategy to optimize the inspection and maintenance schedules of bridges, and extend their lifespans. One of the main challenges of automated damage detection is the lack of data on damaged states, which makes it difficult to validate new approaches in the research and development stage. To alleviate this problem, a monitoring campaign on a two‐span test bridge with defined defects is conducted and documented in this article. The bridge is a steel‐concrete composite structure with a length of 30 m, with two primary steel girders and a segmented concrete deck. The recorded data capture the long‐term ambient data from 18 test days and changing environmental conditions, as well as the short‐term ambient data and dynamic load tests from four damage scenarios with well‐defined damage extents. A mobile measurement system with numerous sensors is used for data acquisition. A shaker is placed on the bridge to excite white noise. The main goal of this article is to document the experimental procedure and perform preliminary plausibility checks on the measured data. First results demonstrate that system response data and environmental conditions are recorded reliably and that environmental effects significantly affect the long‐term measurements. Therefore, a suitable data set is provided as open‐source data for future studies on data normalization and automated damage detection.
