“…3a, based on the experiment carried by Yu et al (2011) [24], and it is found that the modified pinching hysteresis can well predict the hysteretic responses. The self-centering hysteresis and SC-SPSW model are verified through the specimens of SC-SPSW-1 and SC-SPSW-4 in Reference [7]. Again both hysteretic responses can be well matched by the self-centering hysteresis and the combination of self-centering and pinching hysteresis, respectively.…”

“…After that, the interfaces in the rocking connection detach, elongating the PT elements and the energy is dissipated by the infill-thin web plates. 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.…”

“…However, the frame will expand due to the elongation of the beams since the beam rotate at their flanges, and the expansion beyond a certain level can induce failure in the perimeter self-centering frame and excessive cracks in the slabs [5,6]. As an alternative solution, an innovative dual frame-wall resilient system consisting of a high-strength moment-resisting steel frame (HS-MRF) and selfcentering steel plate shear walls (SC-SPSWs) is proposed [7], as shown in Fig. 1.…”

“…The HS-MRF work provides larger resistance to lateral forces but remains elastic during both IO and DC levels, and the SC-SPSW ensures recentering capability at the DC level by using the PT elements. More details can be found in the previous paper [7].…”

“…To this end, this paper first summarised the hysteresis and proposed the analytical expressions Figure 1: Dual frame-wall resilient system [7] for the steady-state response and the corresponding stability of a nonlinear oscillator subjected to harmonic excitation considering viscous damping, followed by the discussion of dynamic behaviour of the dual frame-wall system. The findings shed light on the inherent dynamic properties of the dual frame-wall system and suggest that a reasonable combination can achieve a favourable seismic performance.…”

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.
