【摘要】 结构影响系数体现了不同结构类型的地震作用折减,一般认为结构影响系数与结构的延性水平、结构的超强相关。根据我国《建筑抗震设计规范》(GB50011-2001),设计了两个单层框架结构。选用8条地震波记录,采用ANSYS软件进行动力时程分析,得出结构的延性水平、超强水平以及结构影响系数,并提出单层钢框架结构的结构影响系数的建议值。更多还原

【Abstract】 The structure influence factors reflect the reduction of the earthquake action of different structure cat-egories.Generally speaking,the structure influence factors are related with the ductility level and overstrength of the structure.Based on Chinese Seismic Code(GB50011-2001),two models of one-story steel frames are de-signed.Time-history dynamic analysis is carried out by the ANSYS software to analyze the models with records of eight seismic waves,the ductility level,the overstrength and structure influence factors are derived.The paper also suggests the value of the structure influence factors of one-story steel frames.更多还原
