摘要

Because of their better seismic performance, double corrugated steel shear walls (DCSSW) have now become a viable substitute for regular corrugated steel shear walls (CSSW). CSSW is typically used in both horizontal and vertical orientations. However, a new and innovative type of DCSSW, known as orthogonal double corrugated steel shear walls (O-DCSSW), has been recently proposed. This paper is dedicated to exploring the lateral behavior of these promising O-DCSSWs under cyclic loading, with the potential to enhance seismic performance significantly. When compared to vertical and horizontal DCSSWs and CSSWs, the results showed that O-DCSSWs had better strength and energy dissipation. The maximum strength of O-DCSSW is greater than that of DCSSW with vertical and horizontal orientations by 10.1% and 23.8%, respectively. Also, energy dissipation in the O-DCSSW model is greater than that of DCSSW with vertical and horizontal orientations by 10.7% and 31.4%, respectively. The arrangement of bolts significantly influenced the hysteresis behavior of O-DCSSWs. Additionally, it was shown that O-DCSSWs’ seismic performance is negatively impacted by decreasing corrugation depth, and their strength and energy dissipation are negatively impacted by increasing corrugation wavelength.
