[提要]  以实际算例分析了在美困北岭地震和日本阪神地震中，数百幢多高层钢结构房屋的梁柱刚性连接节点受到严重破坏的根本原因，提出在钢结构梁柱节点抗震设计中必须遵守的两个基本原则，同时还推荐了几种具有良好抗震性能的梁-柱刚性连接节点。
[关键词]  梁-柱刚性连接节点  常用设计法  栓焊连接  强节点弱杆件  延性

The damage of column-bcam rigidity joints in hundrcds of multi-story and high stccl buildings in the Northridge carth-quake and the Hanshcn carthquake is analyzcd by a calculating cxamplc. The strong joint principlcs which must be complicd with in ascismatic dcsign arc prcscntcd. The authors also rccommcnd some kinds of column-bcam joints which have good ascismatic charactcristics, such as wclding slabs on the flangcs in the bcam's cnd, widcning the width of the flangcs in the bcam's cnd, hcightcning the hcight of the bcam in its cnd.
