摘　　要：利用ABAQUS软件对RC异形柱框架节点进行数值分析,假定钢筋和混凝土之间存在有效粘结,建立"拉伸强化(Tension Stiffening)"模型来考虑裂缝之间混凝土和钢筋的约束关系,通过变化"拉伸强化参数"来研究T形、L形、十字形柱节点的受力情况,获得三种类型柱节点的强化参数建议值,为同类型的异形柱模拟方法提供一定的理论基础。This paper doing numerical analysis of nodal force performances of RC frame structure with special-shaped columns using ABAQUS software, assuming the bonding between reinforcement and concrete is effective, the establishment of a ＂tension stiffening＂ model is to consider the constraint rela- tion between the cracks of concrete and reinforcement, to research nodal force performances of T shape, through changing ＂tensile strengthen parameters＂ L shape, cross-shaped columns, finally getting parame- ter suggested values of three types of columns, and providing certain theoretical basis for the same type of special-shaped columns simulation methods.

关 键 词：拉伸强化参数 后继破坏 模拟技术
