【摘要】 根据结构类型、延性等级以及结构的超静定次数的不同考虑了不同程度的超强,并对超静定次数偏少的结构采用偏低的地震力降低系数。通过对严格按照我国规范设计的单层单跨框架结构进行非弹性动力反应分析,发现单层单跨框架结构保守的超强值可达2.0。更多还原

【Abstract】 Account overstrength coefficient which varies from structure type,ductility degree and degree of statical indeterminacy,and suggest smaller overstrength coefficient for these systems which have lesser degree of statical indeterminacy.In this article,we have studied the overstrength of single-story and single-bay frames which are designed strictly conforming to current Chinese codes and acquired the conservative overstrength of those systems is up to 2.0.更多还原
