摘　　要：通过对防止楼板连续倒塌原理的分析,提出如果将我国《建筑抗震设计规范》(GB50011—2001)建议的公式(6.6.9)同时应用于中柱节点、无边梁的边柱节点和角柱节点,公式中的NG应改为该层楼板重力荷载代表值作用下的中柱轴压力设计值。指出在罕遇水平地震作用下,板柱节点发生冲切破坏后,板柱结构的变形呈现弯曲型,并通过算例进行了验证。Based on the analysis of the principle of preventing slab progressive collapse, it is reckoned if the formula （6.6.9） suggested by Code of Seismic Design of Buildings （GBS0011-2001）applies to interior connection, exterior connection and corner connection without spandrel beam, NG in the formula should be modified as the design value of axial compressive force in the interior column under the representative value of gravity load of the floor. It is pointed out and verified by an example that the deformation of flat plate structures is flexural after punching failure of slab-column connection happened under severe earthquakes.
