Finite Element Analysis On The Mechanical Behaviors Of New Cross-slanted Corrugated Steel Plate Shear Wall

Abstract

In order to study the mechanical behaviour of the cross-slanted corrugated steel plate shear wall, the performance of the wall under one-way loading and low cycle loading was analyzed using the finite element analysis software ABAQUS. And the performance compared between flat steel plate shear wall (FSPW), single inclined corrugated steel plate shear wall (SCSPW) and horizontal corrugated steel plate shear wall (CSPW) was studied. The results show that the effect of self buckling of the models of cross-slanted corrugated steel plate shear wall (CCSPW) is significant due to the interaction of two layers of corrugated steel plates. The yield bearing capacity, ultimate bearing capacity and out of plane deformation of CCSPW are better than those of CSPW, SCSPW and FSPW with the same thickness. The yield bearing capacity is 1.09 times of the same thickness of CSPW, 1.22 times of the same thickness of SCSPW. The ultimate bearing capacity is 1.25 times of the same thickness of CSPW, 1.57 times of SCSPW. And the out of plane deformation is 1/3 of the same thickness of CSPW. Under the low cycle loading, the hysteretic curve of CCSPW is shuttle shaped, full and stable. And there is no obvious “pinching” phenomenon in the whole loading process. Compared with CSPW, SCSPW and FSPW, The CCSPW has better hysteretic performance and energy consumption capacity.
