摘要
半刚性连接是目前高层钢结构建筑中常用的一种梁柱连接形式。采用三参数幂函数模型确定连接的弯矩—转角关系,推导上下翼缘角钢梁柱半刚性连接的初始刚度公式和极限弯矩公式。通过一系列的图表对影响上下翼缘角钢半刚性连接节点的初始刚度和极限抗弯承载力的主要因素进行理论分析,与试验结果吻合较好,为半刚性连接节点的分析设计提供参考。
Most beam-column connections used in multi-story frames are semirigid joints, To represent the nonlinear moment rotation curves ,the three-parameter power model is adopted . The values of initial stiffness and ultimate moment capacity of top and bottom angle iron connection in this model can be determined by a set of homographs. Comparison with test on the joint indicates a good agreement between analytical and experimental results,thus providing a reference for its design in the future.
