“…Finally, the last paper of this particular issue (Vogiatzis and Avdelas, 2018) also focuses on the concrete infill of steel frames and presents the development of a three-dimensional, non-linear finite-element model to assess the structural behaviour of steel frames with reinforced-concrete infill walls subjected to a combination of gravity and in-plane lateral loading. Sensitivity studies, taking into account both material characteristics and geometrical non-linearities were made to study parameters like the shear retention factors, Coulomb's coefficient for steel-concrete contacts and different load-slip relationships for modelling the shear behaviour of headed studs.…”

2 3This is the second part of a two-part themed issue 'Composite (steel and concrete) structures -new developments and trends'. The aim of themed issue is to capture the state-of-the-art in the design of composite structures made from steel and concrete as there has been a boost in the use of composite structures (steel and concrete) worldwide. This second part features seven papers contributed by authors from different countries including Brazil, China, Greece, Iran, Hong Kong, Portugal, and United Kingdom. Authors shared their latest technical assessment on the next Eurocode 4, composite columns, composite connections, steel truss reinforced composite joints, shear connection by adhesion and interlocking & friction, sandwich panel infilled steel frames and composite steel frames with reinforced concrete infill.The first paper by Johnson (2018) presents an overview of the challenges faced in developing the next Eurocode 4 for composite structures. The paper initially describes the nature of comments received and recent information from research followed by a discussion of the priorities for inclusion in Eurocode 4. The main requests are centred on the needs to make it easier to use, to shorten it and to include much new material. This paper also presents examples of where removal of uncertainty and a few deletions would make EC4 more user-friendly. As for the new material, it indicates that priority should be given to the inclusion of provisions which fills gaps in current recommendations. Some requests for extension of scope have also been listed, with reasons given why some of them should not be accepted.The second paper by Zhu and Chan (2018) is a contribution in the field of the novel trend in composite structures, that is the association of steel or high strength steel with high strength concrete (around 100 MPa). The study experimentally and numerically evaluates the axial behaviour of concrete-filled steel tubes (CFST) with triangular, hexagonal and octagonal cross-sections and using high-strength concrete. The paper discusses the impact of cross-section shape on the load capacity and ductility of these CFST sections. The outcome of the experimental studies were also used in the assessment of existing design provisions in European, American and Chinese standards. The paper also presents finite-element models incorporating three existing concrete constitutive models and compares these results to the previously performed experiments. Finally, design approaches for CFST were also reviewed and assessed.The third paper by Rodrigues et al. (2018) evaluates the structural response of composite joints situated in hogging moment regions. An experimental program was proposed and was centred on the development of an alternative for the standard push out tests. In hogging moment regions the concrete slab is not under compression forces and it can lead to an extensive concrete cracking that may affect the actual structural joint response. An alternative setup (i.e. pull out tests) was developed and described to repre...

“…From the literature reviews presented by the authors [7,8], it appeared that although some reported experimental studies could be found in [11,12], very limited analytical or theoretical investigation was reported on the behaviour of the SRCW-T2 system. On this basis it is necessary to undertake further comprehensive investigations to better understand the flexural behaviour of composite SRCW-T2 systems.…”

“…The generated three-dimensional (3D) finite element (FE) model used to perform the parametric study has been recently developed and validated by the authors (Figure 2b) for computing the behaviour of tested specimens. The details of the 3D FE models and their validation using experimental results are discussed in detail in [7]. These validated models were developed using the Finite Element Method (FEM) and provided further insight into the behaviour of composite SRCW-T2 systems.…”

“…The SRCW system has already demonstrated good resistance during the 1923 Great Kanto, Japan earthquake (1923) [6]. Since then, different design approaches were proposed and some relevant research findings have been reported in recent years as discussed in [7]. Among these, the SRCW system with semi-rigid (SR) connections, could be applicable as a lateral-resistance system for lowto-moderate rise buildings located in earthquake-prone regions as it has the potential to offer strength appropriate for resisting the lateral forces from earthquakes and stiffness adequate for controlling drift [9,10,11].…”

In recent years, there has been a growing interest towards the use of a composite structural system consisting of steel frames with reinforced concrete walls (SRCWs) as an economical alternative within earthquake resistant wall systems. The SRCW system is classified as Composite Structural Systems Type 1 in EN 1998EN -1:2004. It has been shown that the SRCW system has the potential to be applicable as a lateral-resistance system for low-to-moderate rise buildings located in earthquake-prone regions as it has the potential to offer strength appropriate for resisting the lateral forces from earthquakes and stiffness adequate for controlling drift. Within the frame of this paper, analytical studies are conducted in order to obtain a better understanding of the SRCW system structural performance. Numerous three dimensional (3D) nonlinear Finite Element (FE) models have been developed using ANSYS software package. The detailed developed 3D FE models include the horizontal and vertical boundary steel elements, the discrete reinforcing bars, discrete stirrups as longitudinal and transverse confinement reinforcement, the shear connectors, the top and seat angles and the web angles including the bolts. Results and findings of this study are indicative of effectiveness of the headed studs geometry and material properties.

Over the last few years, hybrid steel‐timber components and systems are enjoying increasing popularity in the construction sector, particularly in the case of multistorey timber buildings where significant benefits arise due to faster and safer on‐site erection, improved structural and seismic performance combined with minimized environmental impact. Most of these studies focus on steel frames with Cross‐laminated Timber (CLT) infills and hybrid steel‐timber joints. However, it may only sometime to be possible to satisfy the maximum drift limit prescribed by building codes only with CLT shear walls and hybrid steel‐timber joints. Some promising improvements have been proposed in the literature for improving buckling stability and avoiding excess building drifts. Among these, is a new type of shear wall called the Wood‐Steel Composite Shear Wall, which has much higher stiffness and can drastically reduce the overall building drifts due to the employment of Steel Plate Shear Walls. Regarding the above considerations, this paper assesses the structural behaviour of Wood‐Steel Composite Shear Wall systems via the finite element method. In the developed Wood‐Steel Composite Shear Wal system, glue connects a thin gauge steel web plate to the boundary Laminated Strand Lumber frame. Based on previous experimental studies, finite element modelling was performed to investigate the effects of behavioural parameters on the response of the Wood‐Steel Composite Shear Wall system. It was found that the plate wall thickness has a significant effect on the initial stiffness and the peak capacity of this system, while changing that parameter may not change the failure mode of the system.
