钢梁-钢筋混凝土柱组合结构(RCS)能够充分利用钢与混凝土材料的强度、刚度及延性等性能的优势。提出一种新型钢梁-钢筋混凝土柱全钢连接形式,采用有限元分析软件ANSYS对连接节点进行分析。结果表明:钢梁端部优先屈服,随后钢柱端部屈服,实现“强柱弱梁”的设计理念,且节点区采用全钢构式,延性耗能能力较好。分析了节点的受力机理,提出了节点设计的建议。
Steel girder - RC column composite structure (RCS) can take full advantage of the strength, stiffness and ductility properties of steel and concrete. A new type of steel girder-steel reinforced concrete column steel connection was proposed. The connection nodes were analyzed by finite element analysis software ANSYS. The results show that the end of the steel beam preferentially yields, and then the end of the steel column yields, which realizes the design concept of “strong column and weak beam”. The all steel structure in the node area has good ductility energy dissipation capability. The stress mechanism of the node is analyzed and the design of the node is proposed.
