摘　　要：在不同的结构体系中,节点刚域对于结构的整体刚度和构件的内力计算都有一定的影响。而在框架结构中,节点刚域的影响尤为显著。现以实际工程为例,对比了高烈度区在地震工况下,梁端、柱端的节点刚域在均考虑、均不考虑和只考虑其中一个时,四种情况下的结构模型,从而对考虑节点刚域后结构整体刚度和构件的内力进行了分析研究。In different structural systems,node rigid zone has certain impact upon the structural integrity rigid and internal component force calculation.As for frame structure,the impact of node rigid zone is particularly great.Taking an actual engineering as an example,by comparing the structural models in the high intensity region under seismic conditions,when the joint stiffness domain of the beam end and the column end are both considered,neither considered nor considered,and only one of them is considered,it analyzes and studies the overall stiffness of structure and the internal forces of the members after considering the joint rigid region.
