超高层钢结构建筑采用钢管混凝土柱是目前较为常用的一种结构形式,与钢管混凝土柱连接的梁有钢梁、劲性梁或混凝土梁等多种方式。目前钢管混凝土柱与型钢混凝土梁节点的研究较少,针对钢牛腿式钢管混凝土柱与型钢混凝土梁的连接节点,对受力性能进行了1∶2缩比例的试验研究,同时采用了ANSYS有限元软件进行分析。结合试验结果和有限元分析结果,研究了该节点的受力特性,结果表明,该节点有很好的极限承载力和抗震性能。
The use of CFST columns in super high-rise steel structures is one of the most commonly used structural forms at present. Beams connected with CFST columns include steel beams, stiff beams or concrete beams. At present, there are few researches on the joints of CFST columns and SRC beams. For the connection nodes of SRC columns and SRC beams, the 1: 2 contraction ratio of the RC columns is studied experimentally. At the same time, Meta software for analysis. Based on the test results and finite element analysis results, the mechanical behavior of this joint is studied. The results show that this joint has very good ultimate bearing capacity and seismic performance.
