介绍了位移型阻尼器消能减震结构在多遇地震下的计算分析方法。针对某框架结构，布置16组防屈曲耗能钢板墙加固改造，采用ETABS2013软件进行了多遇地震快速非线性分析和罕遇地震静力弹塑性分析。通过比较分析结果，多遇地震下防屈曲耗能钢板墙屈服耗能，提高结构阻尼比，降低地震力的输入，结构层间位移角有所减小并满足规范要求。罕遇地震下结构抗震性能显著提升。

The effective analytic way provided for the calculation of energy dissipation structure of dis-placement-based dampers under frequent earthquakes was introduced in this thesis.According to the frame structure, an 16 buckling restrained steel plate shear wall was arranged to retrofit it. In addition, the ETABS2013 was adopted to carry on the fast nonlinear analysis under frequent earthquakes and static elastic-plastic analysis under severe earthquakes.By comparing the results of analysis, the buckling restrained steel plate shear wall can yield energy dissipation under frequent earthquakes.As a result of increasing structural damping ratio and decreasing the input of seismic force, the story drift was decreased and met the standard re-quirement and the anti-seismic property was significantly improved under severe earthquakes.
