（中國建筑標(biāo)準(zhǔn)設(shè)計研究所 北京 100044）[提要] 以實際算例分析了在美困北嶺地震和日本阪神地震中，數(shù)百幢多高層鋼結(jié)構(gòu)房屋的梁柱剛性連接節(jié)點受到嚴(yán)重破壞的根本原因，提出在鋼結(jié)構(gòu)梁柱節(jié)點抗震設(shè)計中必須遵守的兩個基本原則，同時還推薦了幾種具有良好抗震性能的梁-柱剛性連接節(jié)點。

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.
