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。
Combined with the construction characteristics of Longmen Bell Tower in Luoyang, this paper proposes a structural approach to the cornice column reception in traditional style, namely the construction of the receiving node of reinforced concrete column under the concrete filled square steel tube column. Through the comparison of three different calculation models and the overall indexes, the results show that the connection properties of square concrete filled steel tubular columns lie between the hinged joints and the rigid joints, which are semi-rigid joints. Simplified control of the overall structure should be taken to calculate the control of hinges, just calculate the assumed intermediate value. According to the relevant requirements of Technical Specification for Concrete-filled Steel Tube Structure (GB 50936-2014), the bearing capacity of the concrete-filled steel tubular column under single stress state and complex stress state is checked. The results show that the concrete filled square steel tube column meets the requirements of various stress conditions Performance requirements. Through the analysis of the whole and local nodes, it can be known that the structure node is safe and reliable, and can be used for reference of similar project design.
