矩形钢管柱下伸地下室层的节点设计研究

Research on Joint Design of Basement Floor with Rectangular Steel Pipe Column Extending Downward

介绍了两种钢结构中矩形钢管混凝土柱下伸地下室时于地下室顶板处钢柱与钢筋混凝土梁连接的节点做法。根据工程实际情况对规范和标准图集做法提出优化方案,并提出相应具体的设计措施。通过钢筋拉拔试验验证该节点的焊接可靠性,为相关工程设计提供理论依据和实践经验。

This paper introduces the practice of connecting steel columns and reinforced concrete beams at the top of the basement of rectangular steel tube concrete columns in two types of steel structures.Based on the actual engineering situation,optimization schemes for specifications and standard drawing practices are proposed,along with corresponding specific design measures.The welding reliability of this joint is verified through reinforcement tensile tests,providing theoretical basis and practical experience for related engineering designs.
