带环筋的穿心暗牛腿钢管混凝土柱节点有限元分析

The finite element analysis in CFST connection with ring steel and steel brackets through tubular core

介绍了带环筋的穿心暗牛腿钢管混凝土柱节点的有限元分析结果,并与试验结果进行了比较,数据表明有限元能较好模拟节点受力情况,可以作为试验的有效补充进一步分析节点的受力机理。从试验及有限元两方面均表明此带环筋的穿心暗牛腿钢管混凝土柱节点是一种传力直接、延性好、施工方便、有良好工程应用前景的节点。

By comparing experiments results with the nonlinear finite element analysis（FEA）, it is proved that FEA can simulate the experiments properly and can be an effective complement to the experiments. Both experiments and the FEA show that this joint without ring beam can transfer the load directly, and has a good mechanics function. And because of the convenience of con- struction, this joint can applied widely.
