【Abstract】 The effective analytic way provided for the calculation of energy dissipation structure of displacement- 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 requirement and the anti- seismic property was significantly improved under severe earthquakes.更多还原
