Restoring Force Model Investigation of Short Pier Shear Wall

Abstract

To study the seismic behavior of short pier shear wall, 6 short pier shear wall specimens are tested under low cyclic loading with axial load ratio of 0.2. Hysteretic rules and stiffness degradation rate are determined base on test results and feature points are defined by theory, restoring force model that considers the effect of two loading direction to hysteretic characteristics is proposed based on test research, which could be applied to the nonlinear dynamic analysis of the structure.
