“…To capture the material's nonlinearity with accuracy, Hill's yield criterion (Hill, 1948;Hill, 1998) has been selected to describe the anisotropic plastic behaviour of the cross-laminated timber. The accuracy of Hill's model for capturing the non-linear behaviour and failure mode of timber has been previously investigated by (Xu et al, 2014;Vogiatzis et al, 2020).…”

Frontiers is more than just an open access publisher of scholarly articles: it is a pioneering approach to the world of academia, radically improving the way scholarly research is managed. The grand vision of Frontiers is a world where all people have an equal opportunity to seek, share and generate knowledge. Frontiers provides immediate and permanent online open access to all its publications, but this alone is not enough to realize our grand goals. Frontiers journal seriesThe Frontiers journal series is a multi-tier and interdisciplinary set of openaccess, online journals, promising a paradigm shift from the current review, selection and dissemination processes in academic publishing. All Frontiers journals are driven by researchers for researchers; therefore, they constitute a service to the scholarly community. At the same time, the Frontiers journal series operates on a revolutionary invention, the tiered publishing system, initially addressing specific communities of scholars, and gradually climbing up to broader public understanding, thus serving the interests of the lay society, too. Dedication to qualityEach Frontiers article is a landmark of the highest quality, thanks to genuinely collaborative interactions between authors and review editors, who include some of the world's best academicians. Research must be certified by peers before entering a stream of knowledge that may eventually reach the public -and shape society; therefore, Frontiers only applies the most rigorous and unbiased reviews. Frontiers revolutionizes research publishing by freely delivering the most outstanding research, evaluated with no bias from both the academic and social point of view. By applying the most advanced information technologies, Frontiers is catapulting scholarly publishing into a new generation. What are Frontiers Research Topics?Frontiers Research Topics are very popular trademarks of the Frontiers journals series: they are collections of at least ten articles, all centered on a particular subject. With their unique mix of varied contributions from Original Research to Review Articles, Frontiers Research Topics unify the most influential researchers, the latest key findings and historical advances in a hot research area.

“…The type 2 wood steel composite shear wall system, WSCSW-T2, has been recently developed and validated by the authors (Figure 3) for computing the behaviour of tested specimens. The details of the generated 3D numerical models and their validation using experimental results are discussed in detail in [4]. These validated models were developed using the Finite Element Method (FEM) and provided further insight into the post-elastic behaviour of WSCSW-T2 systems.…”

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.

“…The numerical model could not be validated against experimental results since there is lack of available experimental data of the same hybrid system in the international literature. Therefore, the authors used as a guide a numerical model of a similar hybrid system that they had built in a recent study (Vogiatzis et al, 2020) which had been validated using experimental data found in (Conrad and Phillips, 2019). Material parameters and techniques used in that model were employed in the current numerical simulation to ensure the validity and accuracy of the model.…”

“…To sum up, the numerical model used to simulate the bare steel frame, as shown in Figure 3B, had been Frontiers in Built Environment frontiersin.org already validated against experimental results by (Vogiatzis, 2019). The CLT shear walls were modelled based on the methodology developed by (Vogiatzis et al, 2020) for a similar steel-timber hybrid system under monotonic loading which had been validated using experimental data. It has been shown in the literature that the Hill's criterion, as implemented in ANSYS, once validated for monotonic loading then it has the ability to be used for the investigation of the same specimen under cyclic loading conditions without further calibration on new inputs required (Rahmzadeh and Iqbal, 2021).…”

Behaviour and capacity of cross-laminated timber (CLT) infills built inside steel frames have been given increasing research attention in recent years. It is widely accepted that when the CLT wall panel is built in tight contact with the bounding steel frame to participate in the load sharing, its inherently large in-plane stiffness will attract additional forces to the frame area and change the behaviour of the hybrid system. If not designed properly, the structural integrity of both the infill and the frame will be compromised. It is thus crucial to accurately evaluate the contribution of the infill CLT wall panel to the stiffness and strength of the hybrid system. To that end, a finite element study was performed to investigate the frame-wall interaction effect on the behaviour of hybrid systems. The lateral stiffness, lateral load capacities and hysteretic characteristics of the hybrid systems with frictional and connected interfaces were investigated. The load-sharing effect between the CLT wall and the steel frame was studied. The numerical results showed that the connected models were very effective as the infill absorbed a substantial part of the lateral load, during the initial stages of loading.
