在理论分析和试验结果基础上,推导并提出了钢管混凝土结构梁柱节点的抗剪承载力计算公式。公式不仅考虑了节点的实际受力状态,而且考虑了钢管和混凝土的组合作用。最后,给出了公式的适用范围,可供设计人员参考。
Based on the theoretical analysis and experimental results, the formula for calculating the shear strength of beam-column joints of CFST structures is derived and proposed. The formula not only considers the actual stress state of the node, but also considers the combined effect of steel pipe and concrete. Finally, the applicable range of the formula is given, which can be used as a reference for designers.
