Abstract


Earthquake frame supported shear wall structure with a conversion layer to set the height of the different exhibit different seismic response ; conversion layer and lower stiffness than the seismic performance of the structure have a major impact . In addition , in a rare earthquake shear wall structures supported the elastoplastic stage elastoplastic seismic response of structures with linear response is also very different . Firstly, elastic seismic response analysis of shear wall structures supported . Calculate the number of combinations of different vibration modes of the seismic response of the structure , to analyze the number of select reasonable modes ; SAP2000, high conversion layer structure flexible conversion layer, set the height of the seismic performance ; change the conversion layer stiffness ratios were calculated summarizes the changes in stiffness ratio of the seismic performance . Then , pushover analysis of shear wall structures supported study the seismic capacity of the structure under rare earthquake and damage . Finally, the performance - based seismic design method . Analysis of the numerical results show that the shift on the position with the conversion layer layer displacement and story drift angle curve , and control of the conversion layer , under equivalent stiffness ratio can effectively control the layer displacement and layer the drift angle mutations .
