摘要
结构影响系数取值与结构的延性和超强有关。我国现行《建筑抗震设计规范》(GB50011-2001)对不同的结构体系采用单一的结构影响系数,不尽合理。本文采用时程分析的方法,对按该规范设计的6个不同层数的抗弯钢框架进行分析,得出了相应的结构影响系数,为相应规范的修订提供参考。
The structural influencing coefficient value is correlated with the structural overstrength and structural ductility. In our current Code for Seismic Design of Building, the single structural influencing coefficient is adopted for the different structural systems, which is unreasonable. This paper analyzes six different moment resisting steel frames designed according to ＂Code for Seismic Design of Building＂（GB50011-2001） and gets the corresponding structural influencing coefficient by Timehistory analytical method, which can provide reference for the related code revision.
