摘　　要：首先完成了取自实际工程的两个╋字形穿心暗牛腿式钢管混凝土柱节点的足尺试验 ,检验了这种柱节点的承载能力和破坏形态。随后进行了 7个不同形式的节点模型试验 ,通过变化节点中的环梁、板、穿心牛腿等参数 。A series of tests has been carried out. In the first part of the tests, two full-scale specimens of concrete-filled steel tube connections with steel corbels through the core from a practical project were tested, and then the results regarding the attainment of the ultimate capacity and the collapse model were presented. In the second part of test, seven reduced-scale specimens with various connection details were tested. The results were discussed in light of improving and optimizing the details of the connections.
