Abstract

Macroscopic models, such as Equivalent Beam Model (EBM), Equivalent Truss Model (ETM), Three-Vertical Line Element Model (TVLEM), Multi-Vertical Line Element Model (MVLEM) and Fiber Model, are developed to simplify shear wall element in nonlinear seismic response analysis of reinforced concrete shear walls. The state-of art of macroscopic model is reviewed in detail. Hysteresis model of shear stiffness, flextural stiffness and axial stiffness and corresponding hysteresis parameter selection in macroscopic model are discussed. The problems existing in analytical models and further studies on the subject are pointed out.
