摘　　要：介绍了国内外有关规范对板柱连接侧向变形性能的相关规定,并对其差异进行了比较,讨论了重力荷载对板柱连接抗震性能的影响,结合国内外有关文献试验成果,提出了基于我国规范的板柱连接重力剪力比限值条件,通过工程算例和结构弹性分析,指出重力荷载对板柱结构的抗震性能有较大的影响,在板柱-剪力墙结构的分析设计中,不仅需要考察板柱连接的承载力,同时还应通过限制重力剪力比来控制其极限变形。On drift capacity of slab-column connection, the code provisions of GB 50011 and UBC 97 and the difference are introduced. By reviewing and analyzing the results of a large number of previously reported tests on slab-column connections, an limited gravity shear ratio on China code is presented. Based on structural analyzing and design examples, a design measure of slab-column shearwall structure is proposed.
