| 摘 要： | 鉴于我国规范对异形截面柱或荷载面的冲切强度计算未作明确规定，根据所进行的柱截面为三种典型异形柱(十字形、T形和L形)板柱连接冲切特性试验成果，并结合献试验资料以及国外规范的作法，提出了符合我国设计实践的非矩形截面柱的板柱冲切强度计算模式．同时根据大量试验资料提出了适用于不同柱型的冲切强度计算公式，该公式不仅形式简单，且同ACI318规范及我国GB50010—2002规范方法相比，与不同试验结果的符合度均较好．

| Abstract: | The reinforced concrete slabs with three kinds of typical special-shaped columns (cross-shaped section, T-shaped section and L-shaped section) were tested. Based on the results and literatures, a method for calculating critical perimeter of nonrectangular column and predicting the punching strength of slab with column in different shape was proposed. The proposed method of prediction is relatively simple to use. Comparing with the methods advocated by present codes of China and ACl, the results have better correlation with the various test results by means of this method. |
