摘要
探讨了型钢混凝土梁与钢管混凝土柱节点的外加强环板受力特性,基于既有的试验结果和理论计算,分析了加强环板的应变分布规律,研究了环板宽度对节点的承载力和刚度的影响,并通过建立承载力—变形双控原则来确定外加强环板尺寸的计算公式。
The study, on joint of CFST columns to SRC beam connections with outer annular-stiffener. Based on the present researches and theoretical deduction, the mechanical behaviors of outer annular-stiffener are analyzed. The influence of annular-stiffener on the bearing capacities and stiffness of the joint is discussed. According to different failure states load-bearing capacity and maximum crack width), the formulas of outer annular-stiffener width is built up.
