| 摘 要： | 共进行了6个大比例尺板柱节点在竖向荷载和水平反复荷载作用下的试验，在对板柱节点试验结果分析研究的基础上，采用塑性极限方法，对钢筋混凝土板柱节点在冲切力和不平衡弯矩共同作用下的承载能力进行了研究，推导出板柱节点抗冲切和抗弯强度相关方程，并简化为实用计算公式。与本文作者和国内外有关试验数据的比较表明，本文提出的计算公式具有较高的精度。

| Abstract: | Three interior and three edge slab-column connections were tested. The properties of connections under vertical and lateral reversed load were analyzed. The plastic limit state method was used to analyze the slab-column connections under the combined action of punching shear and unbalanced moment. A set of equations was derived and simplified to practical formulas in the paper. Comparison of the theoretical with the experimental results show that the present method can precisely predict the ultimate strength of reinforced concrete slab-column connections under the combined action of punching shear and unbalanced moment. |
