| 摘 要： | 结构的地震作用取值与结构的延性和超强有关,结构的延性和超强可用结构影响系数来反映。我国现行抗震设计规范对不同材料的所有结构体系采用单一的结构影响系数,不尽合理。文章针对三个不同的抗弯钢框架,采用Pushover分析方法,得出了多层抗弯钢框架的结构影响系数,可供工程设计人员参考。

| Abstract: | The structural earthquake action value is correlated with the structural overstrength,structural ductility and overstrength can be reflected by the structural influencing coefficient.It is unreasonable that the single structural influencing coefficient is nowadays adopted by currently code for seismic design of buildings in all structural systems built by different materials in our country.In this paper,three examples are presented to get the structural influencing coefficient by Pushover analytical method,which can be of some reference for designers. |
