【摘要】 在钢筋混凝土框架结构地震反应分析中,梁柱节点区域因具有相对较大的刚度而设置一定范围的刚域,其设定方法对结构的地震响应和损伤发展历程具有明显的影响。采用基于柔度法的纤维有限元方法考察了不同的刚域设置方法对结构地震反应和损伤发展的影响,并结合我国抗震设计的实际情况给出了相应的设计建议。更多还原

【Abstract】 The ends of reinforced concrete(RC) frame members are often modeled with rigid zones in the response analysis of RC frame structures,considering the relatively large stiffness of node panels.The seismic response and damage progress of RC frame structures are significantly influenced by the settings of rigid zones.In this paper the effect of different setting methods for rigid zones is investigated by flexibility-based finite fiber element analysis,and advices are also proposed with the design practice in China taken into account.更多还原
