FEM Analysis and Seismic Design of Steel Plate Shear Wall Structure

FEM Analysis and Seismic Design of Steel Plate Shear Wall Structure

In recent years, several researchers have confirmed that steel plate shear wall(SPSW) is a very effective energy-dissipating element which reduces the seismic responses of building structures. However, detailed ABAQUS analyses made for large-scale test specimens are rather limited. For this purpose, this study is developed to conduct FEM model development and to make detailed comparisons between FEM and test results. ABAQUS analysis is used first to investigate the overall behavior of the three single-story single-bay SPSWs tested at NCREE. It is illustrated that the hysteretic responses of the three SPSW specimens can be simulated accurately by using a tri-linearly combined isotropic and kinematic hardening material model. In addition, it was found that the FEM model without restrainers had an elastic stiffness of 607MN/radian, and therefore, resulted to a 5% overestimate of the experimental stiffness.
