［摘要］结合洛阳龙门钟楼建筑特点，提出了一种针对传统风格建筑檐口柱收分的结构构造做法，即方钢管混凝土柱下接钢筋混凝土柱收分节点构造。通过3种不同的计算模型分析及整体指标对比，结果表明方钢管混凝土柱连接属性介于铰接与刚接之间，属于半刚性连接。结构简化计算时整体控制指标应取铰接、刚接计算假定的中间值。根据《钢管混凝土结构技术规范》（GB 50936—2014）相关要求验算该构造下方钢管混凝土柱在单一受力状态和复杂应力状态的承载力，结果表明方钢管混凝土柱满足各项受力状态下的性能要求。通过整体与局部节点分析可知，该构造节点安全可靠，可供类似项目设计参考。

Abstract:According to building characteristics of  Luoyang Longmen Bell Tower, a structural construction was proposed for cornice column joint of traditional style building, that is  joint structure of concrete-filled square steel tubular  column lower connected with reinforced concrete column. Through the analysis of three different calculation models and the overall index comparison, the results show that the connection property of the  column of concrete-filled square steel tubular short column is between the hinge and rigid connection, and it belongs to semi-rigid connection. In the structural simplification calculation, the overall control index should take the intermediate value of the calculation assumptions of hinge and rigid connections. According to the relevant requirements of Technical code for concrete filled steel tubular structures(GB 50936—2014), the bearing capacity of concrete-filled square  steel tubular  columns under single stress state and complex stress state was verified. The results show that the concrete-filled square steel tubular  columns meet the performance requirements under different stress states. Through the analysis of the whole and local joints, it is verified that the constructed joint is safe and reliable, and it can be used as reference for similar project design.
