[摘要]結構在中震下允許進入彈塑性階段,常規(guī)的設計很難對結構進行中震下的性能控制。為實現基于中震的性能化設計方法,通過對6組鋼框架鋼板剪力墻結構進行Pushover分析,得到了不同性能指標下地震力調整系數建議值。利用地震力調整系數,提出了鋼框架鋼板剪力墻結構基于中震的性能化設計方法。算例結果表明,利用該方法可有效地對鋼框架鋼板剪力墻結構進行中震的性能化設計。

Abstract:The structure is allowed into elasticplastic stage under moderate earthquake, so the conventional design is very difficult to control the moderate earthquake performance. In order to implement the performance based design method under moderate earthquake, the seismic force modification factor was got under different performance indicators through the Pushover analysis of six steel framesteel plate shear wall structures. The performancebased seismic design method of steel framesteel plate shear wall structure for moderate earthquake was proposed using the seismic force modification factor. The results show that this method can be used to performancebased design under moderate earthquake effectively for steel framesteel plate shear wall structures.
Keywords:steel frame\|steel plate shear wall; seismic force modification factor; static Pushover analysis; moderate earthquake; plastic hinge; performance based design
