| Abstract: | According to the characteristic of shear wall structure, its performance level is divided into three levels, which are serviceability, life-safety, and collapse prevention. The three levels are qualified with storey drift ratio. Applying the inverted triangular distribution of lateral force to the cantilever wall with identical section, the displaced shape is regarded as the initial lateral displacement mode of shear wall structure. For the serviceability and collapse prevention performance levels, it is assumed that the curvature at the bottom cross section of the first storey of the shear wall structure reaches yield curvature and ultimate curvature, respectively. Then, the target displacement mode of the two performance levels can be obtained. Based on the target displacement mode of shear wall structure in the serviceability performance level, the effective parameter, the base shear Vb and horizontal earthquake force Fi at each floor of the building can be determined, and then the structural members can be designed to satisfy strength demand and details of seismic design. Finally, the designed structure is analyzed with nonlinear static analysis procedure and is adjusted by the pushover analysis result until it is satisfied. | |
