ABSTRACT
A high-rise shear wall building structure in Chengdu, Sichuan Province, is analyzed by means of static-dynamic analytical method. The method combines nonlinear static analysis of 3D model with nonlinear time history analysis based on flexure-shear storey model. First of all, nonlinear static analysis method is applied to 3D model of the structure and the storey restoring force curves are obtained. On the basis of the flexure shear storey model, elasto-plastic analysis is carried out by the nonlinear time history method. Finally, the vibration-absorptive analysis of the structure with nonlinear viscous fluid damper under earthquake is performed. The results show that static-dynamic analytical method can be applied to evaluate the overall elastic-plastic seismic performance of the structure and provide a reference for engineering design of similar projects.
Keywords: Energy-dissipated design, Flexure-shear storey model, High-rise buildings, Shear wall structures, Static-dynamic analytical procedure, Storey model.
