摘　　要：作为一种新型的节点连接形式,钢管混凝土(CFST)柱-钢梁单边螺栓端板连接在力学性能上表现优异,在工程实践中使用便捷,一直是国际上研究的热点.明确节点极限承载力对预防节点发生脆性破坏起着关键作用.为探索该节点的受力机理,根据各组件的受力特性,通过建立力学模型推导了各组件的极限承载力,再经单因素分析法进行比较从而得到了最终极限承载力.将这一结果与已有试验结果进行对比,表明该极限承载力计算公式具有较好的适用性.Concrete filled steel tube(CFST)column-steel beam single side bolt end plate connection is a new type of joint connection that is an international hotpot issue,with convenient construction,reliable mechanical properties and other characteristics.The ultimate bearing capacity of the joint plays an important role in avoiding brittle failure of joints,.In order to analyze the stress mechanism of the joint,single factor analysis was conducted in exploring the ultimate bearing capacity of the joint.The ultimate bearing capacity in the past experiment was compared with the theorical result at the bottom of establishing mechanical model,which is shown that ultimate bearing capacity concluded by the calculation formula has a good applicability.
