Abstract

Abstract

The composite shear wall of concrete filled steel tube (CFST) reinforced with corrugated steel plates is a new structural lateral force resistance system. It adopts a design featuring separate load-bearing and lateral force resistance and fully exerts the performance of materials, with a remarkable composite effect. Therefore, the composite shear wall can be used to strengthen the lateral force resistance stiffness of reinforced CFST structures and improve the anti-seismic performance of the structures. In order to study the anti-seismic performance of the composite shear wall, finite element (FE) numerical simulation parameters were first calibrated according to experimental phenomena. Then, in view of the FE simulation results of 12 specimens in three groups, anti-seismic performance parameters such as elastic-plastic force and deformation laws, failure modes, hysteresis characteristics, and energy dissipation capacity were studied when the composite shear wall was subjected to multilevel and horizontal reciprocating loads. Finally, the effect of different axial compression ratios, shear-to-span ratios, and corrugated steel plate thicknesses on the anti-seismic performance of the composite shear wall was analyzed. The results show that the lateral mechanical behavior of the composite shear wall shows a distinct two-stage characteristic. Specifically, it has a full hysteretic curve, slow strength degradation, positive energy dissipation capacity, and high ultimate displacement angle and displacement ductility. In addition, it is found that an increase in axial compression ratio can improve the ultimate bearing capacity, but this will lead to a rapid decrease in the bearing capacity in the second phase. Furthermore, the shear-to-span ratio mainly affects the failure mode of the composite shear wall, and the reasonable height-to-thickness ratio of the corrugated steel plate should vary from 500 to 800.
