摘要
半刚性连接是目前多高层钢结构建筑中常用的一种梁柱连接形式。综合考虑影响节点性能的各个因素 ,对上下翼缘角钢半刚性连接节点的极限抗弯承载力进行了理论分析。通过计算比较 ,得出上下翼缘角钢半刚性连接节点受力的最薄弱环节 ,此最薄弱连接构件的破坏将导致节点丧失抗弯能力。通过计算最薄弱环节的极限承载力 ,可以得出上下翼缘角钢半刚性连接节点的极限抗弯承载力。计算结果与试验结果相比较 ,误差在允许范围内 ,从而验证了分析的可靠性 ,可为半刚性连接节点的设计提供参考。
Most beam-to-column connections used in multi-story frames are semirigid joints. Ultimate flexural resistance of top and seat angle connection is analyzed through considering each factor which influences the behavior of the joint, the failure of the weakest component will result in failure of the connection. Ultimate flexural resistance of top and seat angle connection may be deduced by calculating the resistance of the weakest component of the joint. 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.
