［摘要］对中国、美国和日本三国钢框架结构抗震设计中的梁柱节点设计相关规定进行了比较，比较了三个国家梁柱连接设计、节点域设计、梁柱承载力比要求等内容。并分析了美国WUFW梁柱节点和中国、日本同类节点的区别。通过以上比较，阐明了三个国家对于钢框架结构梁柱节点抗震设计思路、要求、步骤的相同和不同之处。对节点域的承载力计算，美国和日本都考虑了节点域所受轴力的影响；强柱弱梁方面，中国要求低于美国和日本；美国WUF-W梁柱节点的构造和设计方法与中国、日本都不相同。

Abstract:The seismic design provisions of beam-to-column connection for steel frames in China, U.S. and Japan were compared in terms of connection strength, panel zone design, and column-beam relation limitation. The differences of WUF-W  beam-to-column connection of U.S. from similar connections of China and Japan were also discussed. The similarities and differences of seismic design philosophy, requirement and procedure for beam-to-column connection of steel frames in China, U.S. and Japan were clarified. U.S. and Japan considered axial force effect on the panel zone in panel zone bearing capacity. Chinese code requirement was lower than that of U.S. and Japan on principle of strong column and weak beam. The configuration and design methods of U.S.WUF-W beam-to-column connection were different from that of  China and Japan.

Keywords:steel frame structure； seismic design； beam-to-column connection； panel zone design; column-beam relation limitation
