摘要:
通过对型钢混凝土(SRC)柱-混凝土(RC)梁组合件试验现象和测量数据的分析,提出一种较为简化的多分量SRC节点单元模型.该模型的构造方法以节点受力机理为基础,以考虑节点非线性变形特征为目标,可以综合考虑节点区域多种变形,并能应用于组合结构节点的弹塑性全过程分析.结合此单元模型的传力路径与变形组成特点,建立与单元模型相对应的简化计算模型,用于提高模型计算效率.计算与试验结果比较表明,提出的组合结构节点单元模型可以较好地模拟节点的非线性反应,具有较好的计算精度.
Abstract:
Based on the experimental results of the joints of the steel reinforced concrete(SRC) column and reinforced concrete(RC) beam,a new multi-component joint model is proposed.The model considers the two aspects,the resistance mechanism of SRC joints,the nonlinear deformation behavior of the joint respectively,which ca be used to analyze the elastic-plastic overall response of SRC joints.To improve the calculation efficiency,a simplified calculation model is also established,which considers the loading path and deformation behavior of the joint model.The comparison of the experimental and analytical results indicates that this joint model can simulate properly the nonlinear response of SRC joints with good accuracy.
