【摘要】 在钢筋混凝土框架结构地震反应分析中,节点区域因具有相对较大的刚度而设置一定范围的刚域。刚域范围的设定对钢筋混凝土框架结构的地震反应和损伤发展历程具有明显的影响。文章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 seismic 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 effects of different setting methods for rigid zones are investigated by flexibility-based fiber finite element analysis,and advices are also proposed with the design practice in China taken into account.更多还原
