摘　　要：为了克服普通钢管混凝土板柱节点构造复杂的缺点,提出一种全新的节点区柱钢管不连通式钢管混凝土柱-平板节点,并做了8个试件进行抗冲切性能的试验研究。试验结果表明,钢管混凝土板柱节点的开裂荷载、刚度、抗冲切承载力比相同配筋的钢筋混凝土板柱节点略低,但抗冲切承载力试验值大于规范公式的计算结果。In order to overcome the shortage of common CFST（concrete filled steel tubular）column-fiat plate structure, a new type CFST column-slab joint is studied, which keeps the concrete fiat plate continuous and set a pallet by increasing the thickness of the slab partially near the column capital, in which steel hoops are placed. Eight specimens are tested. The main aim is to test the punching shear behavior of CFST column-fiat plate structure in punching shear. The ultimate bearing capacity of specimens is closed to the results which are calculated by Chinese code.
