“…Available investigations on self-centering frame [5,7,[18][19][20][21] show that the prestressed design provides recentering ability, and the pure self-centering frame exhibit trilinear hysteretic relationship. Studies on the infill-thin web plates [22][23][24][25] also find that due to the buckling and plastic deformation, the shear plate shows pinching effect in hysteretic curves. Since the coupling effect between thin web plates and self-centering frame are negligible, the hysteretic behaviour of SC-SPSW is assumed by a trilinear relationship superposed by a pinching relationship.…”

A resilient system comprised of a high-strength moment-resisting steel frame (HS-MRF) and self-centering steel plate shear walls (SC-SPSWs) has been proposed to address the issue of frame expansion. The system's steady-state dynamic responses were analysed using an analytical solution of a single-degree-of-freedom nonlinear oscillator under harmonic excitation, solved via the method of slowly varying parameters. A stability analysis was also conducted to assess the behaviour of singular points. The hysteretic model for the proposed structure is a combination of validated bilinear, self-centering, and pinching hysteresis, representing the high-strength frame, self-centering frame, and steel plate shear wall, respectively. The results indicate that increasing the proportion of bilinear hysteresis has minimal impact on resonance but can decrease nonlinearity for lower excitation intensities. However, for higher intensities, increasing the bilinear hysteresis can significantly decrease peak responses and reduce both the jump and unbounded phenomena. Most of the unstable responses can be divided into four zones, and the unstable regions are greatly influenced by the ratio of hysteretic models. This steady-state dynamic analysis suggests that a well-designed mixture of high-strength moment-resisting steel frames and self-centering steel plate shear walls can bring a favourable seismic performance.

“…Researchers around the world have performed systematic investigations on the factors influencing CFS wall seismic performance, such as type of wall sheathing (Ayatollahi et al, 2020; Buonopane et al, 2015; Gao and Xiao, 2017; Lin et al, 2014; Xu et al, 2021; Yu, 2010; Ye et al, 2015; Zhou et al, 2012; Zeynalian and Ronagh, 2015; Zhang et al, 2021), section and distance of wall stud (Shi et al, 2021, 2022), brace type (Moghimi and Ronagh, 2009; Xu et al, 2021; Zeynalian and Ronagh, 2015), arrangement of self–tapping screw (Ayatollahi et al, 2020; Yu, 2010), wall height–width ratio (Buonopane et al, 2015; Yu, 2010; Zeynalian and Ronagh, 2015), etc. Based on the above research works, two CFS wall failure modes were drawn.…”

“…The above research works have revealed that the application of filling materials effectively improved the seismic performance and shear capacity of CFS walls. Also, some measures have been proposed to improve the buckling behaviors of wall studs, such as the application of double C–section studs in back–to–back (Lin et al, 2014; Nithyadharan and Kalyanaraman, 2012; Shi et al, 2021) and face–to–face (Shi et al, 2022; Wu et al, 2018; Xu et al, 2018b) arrangements. Research has revealed that the buckling responses of square–section wall studs were better than those of studs with other sections.…”

In order to improve the shear capacity and seismic performance of cold–formed thin–walled steel (CFS) walls, in this research, a novel CFS wall filled with phosphogypsum (PG) was developed. Taking PG filling area and covering the wall with sheathing as design parameters, four full–scale test specimens were designed and constructed. Failure mode and seismic performance indexes of each specimen were investigated by performing cyclic loading tests and the effect of PG filler on CFS wall seismic performance was evaluated. Research results showed that PG filler significantly improved the seismic performance and shear capacity of CFS walls. Importantly, the proposed wall presented a remarkable dual–mechanism of lateral force resistance, which was provided by PG filler and wall sheathings, respectively. In addition, analytical models were developed for the calculation of the shear capacity and lateral stiffness of the proposed walls, which presented high prediction accuracy.

“…They found that the connection between the sheathing and the steel keel was a critical factor in determining the failure mode of the CFS shear wall. Shi et al (2022) conducted experimental studies on high-performance cold-formed steel plate shear walls. They found that the shear capacity of composite walls could be significantly enhanced through the use of vertical stiffeners or hat-section end studs.…”

This paper presents experimental studies to investigate the compressive and shear behaviors of cold-formed thin-walled steel-foam concrete composite walls. Three compressive walls and three shear walls were tested. The failure mode and load-displacement curve of the specimen were obtained from the compressive experiment. The compressive wall infilled with foam concrete mainly experienced distortion buckling of the end stud and local crushing failure of the concrete. The stud openings had a limited effect on the compressive bearing capacity of the composite wall. The failure mode and load-deformation curve were obtained in shear tests. The ductility index, shear stiffness, yield load, peak load, energy dissipation, and stiffness degradation were analyzed. The shear composite wall filled with foam concrete mainly occurred concrete crushing failure, local or distortional buckling failure of the end stud, and cracking failure of the calcium silicate board. The shear stiffness, shear capacity, ductility, and energy dissipation of the composite wall could be significantly improved after filling with foam concrete.
