| Abstract: | This article union project actual example , A reinforced concrete frame supported shortleg shear wall structure with special-shaped columns is studied by nonlinear time history analysis. The 3 - D dynamic model, fiber beam element model, wall element model and integration algoritlma of dynamic differentia equation used in elastoplastic seismic response analysis are introduced. The envelope diagram of interstorey drift ratio and distributions of hinges are also obtained. Analysis results show that the application of this kind of structure system is applicable in the area of seismic fortification intensity 6. |
