Abstract
To study the nonlinear mechanical characteristics of reinforced concrete shear wall structures under rare earthquakes, a single reinforced concrete shear wall model is established in SAP2000 program, which is simulated by nonlinear multi-layer shell element. Nonlinear static pushover analysis of the model is presented by uniform acceleration lateral load pattern and inverted triangle lateral load pattern. The relationship curve between base shear and top displacement of shear wall, and the stress distribution diagrams of the concrete layer and rebar layer are obtained. It may be concluded that, the yielding of rebar layer and the cracking of the concrete layer may be observed by stress distribution diagrams. SAP2000 program is feasible to nonlinear simulation of shear wall structures.
