摘　　要：针对减震结构的设计,其振型分解反应谱方法不能反映阻尼器的非线性和结构在大震下的性能;时程分析法需要多次试算、十分繁琐的情况,采用以结构构件设计为主、线性粘滞阻尼器为强度补充的设计思想,将结构等效为单自由度体系,利用基于位移的设计方法对线性粘滞阻尼减震结构进行设计,并利用该方法设计1栋13层框架剪力墙结构,最后通过动力时程分析验证了该方法的可行性。Response spectrum method be used to designing energy dissipation structures can not represent the nonlinearity of viscous dampers and the performance of structures under large earthquakes. Time-history analysis is very complicated, a lot of trial calculations must be required. In this paper a displacement-based design method for vicous damper energy dissipation structures is put forward. The design idea is that the seismic design is focused on the structural components, and the viscous dampers just make up for the insufficiency of the structural strength, and a MDOF structure is transformed into an equivalent SDOF system. A 13-story frame-shear wall structure is designed by this method. The dynamic time-history analysis of the strueture shows reasonability of this method.
