| 摘 要： | 论述了单调荷载下高强钢筋混凝土框架节点的非线性受力性能。高强混凝土选用基于等效单轴应变的增量式正交异性混凝土模型，及高强混凝土单轴受力下的应力-应变关系．钢筋应力-应变关系采用了弹塑性模型，高强混凝土和钢筋之间采用双垂直弹簧模型，编制了二维非线性有限元分析程序，并用此程序计算了在单调荷载下的这4个高强混凝土框架节点试件屈服荷载、极限荷载并绘出骨架曲线，计算结果与试验结果吻合较好。

| Abstract: | In this paper, the analysis of HRC beam column joints under monotonic loading is studied. The incremental orthotropic model based on equivalent uniaxial strain and the stress strain relationship of HRC under monotonic loading proposed by Prof. GUO Zhen hai and postgraduate student XU Jin feng of Tsing Hua University are used. In the stress strain relationship of steel, the ideal elastic plastic model is chosen. A two spring bond element between HRC and steel are adopted. A two dimensional finite element program has been developed for analyzing HRC beam column joints under monotonic loading. The calculated and measured results are shown to be in good agreement. |
