Book Description
Composite Construction in Steel and Concrete IX The highly successful International Conference series on Composite Construction in Steel and Concrete is a major forum for researchers, practitioners, and engineers to share and discuss their research, practical experience and innovations related to composite constructions in steel and concrete. Composite Construction is a key consideration in the design of buildings and infrastructure. Significant advances in research and development have increased the knowledge of the structural performance of composite structures. Some areas are becoming well understood and implemented in the design practice, codes and standards worldwide, while others like, e.g., application of high-performance materials or dismountable and reusable composite members need further studies; trends that are reflected by the conference papers. The 62 contributions contained in this book cover a wide variety of topics, including composite beams, composite columns, composite decks, joints, shear connections, fire behavior, seismic behavior, fatigue and fracture, codification, composite bridges, innovative hybrid structures, numerical investigations and practical applications. The Papers are peer-reviewed by the Scientific Board and may be adapted based on the outcome of the discussions during the conference. This book therefore summarizes the state-of-the-art in composite construction worldwide, as presented at the 9th International Conference on Composite Construction in Steel and Concrete hosted by the Ruhr-Universität Bochum, University of Stuttgart, RPTU Kaiserslautern-Landau and University of Luxembourg, representing the work of authors from 18 countries.

Book Description
Modern Trends in Research on Steel, Aluminium and Composite Structures includes papers presented at the 14th International Conference on Metal Structures 2021 (ICMS 2021, Poznań, Poland, 16-18 June 2021). The 14th ICMS summarised a few years’ theoretical, numerical and experimental research on steel, aluminium and composite structures, and presented new concepts. This book contains six plenary lectures and all the individual papers presented during the Conference. Seven plenary lectures were presented at the Conference, including "Research developments on glass structures under extreme loads", Parhp3D – The parallel MPI/openMPI implementation of the 3D hp-adaptive FE code", "Design of beam-to-column steel-concrete composite joints: from Eurocodes and beyond", "Stainless steel structures – research, codification and practice", "Testing, modelling and design of bolted joints – effect of size, structural properties, integrity and robustness", "Design of hybrid beam-to-column joints between RHS tubular columns and I-section beams" and "Selected aspects of designing the cold-formed steel structures". The individual contributions delivered by authors covered a wide variety of topics: – Advanced analysis and direct methods of design, – Cold-formed elements and structures, – Composite structures, – Engineering structures, – Joints and connections, – Structural stability and integrity, – Structural steel, metallurgy, durability and behaviour in fire. Modern Trends in Research on Steel, Aluminium and Composite Structures is a useful reference source for academic researchers, graduate students as well as designers and fabricators.

Book Description
"Fire is a rare but extreme event that subjects a structure to a unique set of demands. The fire resistance of the structure depends on its ability to resist the combination of the structural gravity loads and the effects of fire without undergoing failure during both heating and cooling. While many studies have been conducted internationally on steel-framed building components in fire, a limited number have focused on composite beams designed according to U.S. codes and standards. This project focused on the thermal and structural behavior of composite beams used in steel building floor systems through both experimental and numerical investigations. These floor systems typically consist of steel beams with a concrete deck cast on top of the beams, where composite action is developed through the use of steel headed shear studs welded to the top flange of the beam. The experimental approach included the use of high-temperature ceramic radiant heaters, vertical loading, and innovative high-temperature instrumentation techniques, including close-range photogrammetry. Isolated concrete slabs representing the concrete portion of the composite floor system were subjected to one-sided heating without the application of load to evaluate the response to a thermal gradient. Large-scale partial composite beams with simple shear beam-to-column connections were then subjected to the combination of heating and loading. There was a reduction in the composite beam load carrying capacity as a result of heating, both at elevated temperatures as well as post-fire ambient conditions. The composite beam was able to sustain service level loads with heating to steel temperatures up to 700°C. Concrete compression failure was an observed failure mode for composite beams with flat slabs at moderate steel temperatures (350-500°C) and overloading. Two modeling techniques were developed and benchmarked using experimental test data: (i) a sequentially-coupled thermal-structural 3D finite element model for evaluating both the thermal and structural response of composite beams and (ii) a 2D fiber-based model for determining the moment-curvature-temperature relationship for a composite beam cross-section. Both approaches account for temperature-dependent material properties and the force-slip behavior of the shear studs. An extensive parametric study was conducted to evaluate the effects of various parameters on the flexural capacity of composite beams at elevated temperatures. Variations in cross-section geometry, concrete deck type and orientation, percentage composite action, and thermal gradient were considered. Current U.S. design provisions for steel-concrete composite beams rely upon a strength-based approach as outlined by the American Institute of Steel Construction (AISC). In partial composite beams, the headed studs transferring interfacial shear between the concrete and steel can undergo significant slip, which is not accounted for directly in design. Results from the parametric study revealed a complex inter-relationship between the beam length, stud slip capacity, and the minimum level of partial composite action that may be permitted for design. A temperature-dependent retention factor was developed for use with the AISC method to predict the flexural capacity at elevated temperatures. Because this retention factor is a function of only the bottom flange temperature, it provides a simple design method to determine the elevated temperature capacity of a composite beam, without having to conduct an extensive thermal and structural analysis." -- Abstract.

Book Description
Composite steel-concrete construction has been widely used around the world. Techniques for the ultimate load analysis and design of composite steel-concrete beams are also well-established and solutions can be obtained with relative ease. However, beams under combined actions such as edge or curved in plan beams subjected to torsion and flexure can be difficult to ascertain their strengths and behaviour due to their complex stress state. These effects of combined actions are not currently addressed in the Australian Standard AS2327.1 (Standards Australia, 2003) or any their international codes. Therefore, this thesis will present two full-scale experimental series to investigate the behaviour of straight and curved in plan composite steel-concrete beams subjected to torsion and flexure with the influence of partial shear connection. Push-out and material tests were carried out to determine the material properties of each component of the composite steel-concrete beams.
