The purpose of this study is to develop non-linear dynamic analysis of RC shear wall subjected to earhquake motions by finite element method. A shear wall is modeled as a quasi-3-dimensional structure composed of plane elements under plane stress condition, and the outplane stiffness of these elements is ignored. A constitutive model of concrete after cracking is assumed to be orthotropic with respect to the crack direction, and to have the origin- oriented hysteretic rule. This rule has no hysteretic enegy consumption. So it is compensated by considering equivalent viscous damping. The acceleration-pulse method is applied to a dynamic procedure, because there is no need for considering unbalanced forces in inelastic regions. This proposed method is applied to the analysis of a H-shaped shear wall subjected to earhquake motions, and the effectiveness of this method is studied by comparing with the test results.
