Discussion on design techniques of seismic reduction and energy dissipation with dampers in building structures
Gao Chengyong, Zhang Jiahua(Shanghai Xiandai Architectural Design Group, Shanghai 200041, China)
Abstract:Dampers can dissipate seismic energy and reduce the seismic effects on the structures effectively, and it has been applied in some projects in China. In order to prompt the application of dampers in China and solve the problems of lacking enough understanding on the applications of dampers, based on several projects, which are mainly designed by Shanghai Xiandai Architectural Design Group and adopted dampers to reduce the seismic effects, it is introduced that velocity-dependent and displacement-dependent dampers and their applications. Based on recent researches and applications in China, some key design problems are studied, some solutions or the endeavor goals in the future are put forward, especially the problems on the application of dampers from the difference between the aseismic codes of domestic and aboard, the analytical techniques upon the structures with dampers, and lateral stability of dampers, etc.. These solutions or goals would benefit engineers.
Keywords:damper; seismic reduction; energy dissipation; design; aseismic computation; ultimate deformation; lateral stability
