［摘要］對(duì)中國、美國和日本三國鋼框架結(jié)構(gòu)抗震設(shè)計(jì)中的梁柱節(jié)點(diǎn)設(shè)計(jì)相關(guān)規(guī)定進(jìn)行了比較，比較了三個(gè)國家梁柱連接設(shè)計(jì)、節(jié)點(diǎn)域設(shè)計(jì)、梁柱承載力比要求等內(nèi)容。并分析了美國WUFW梁柱節(jié)點(diǎn)和中國、日本同類節(jié)點(diǎn)的區(qū)別。通過以上比較，闡明了三個(gè)國家對(duì)于鋼框架結(jié)構(gòu)梁柱節(jié)點(diǎn)抗震設(shè)計(jì)思路、要求、步驟的相同和不同之處。對(duì)節(jié)點(diǎn)域的承載力計(jì)算，美國和日本都考慮了節(jié)點(diǎn)域所受軸力的影響；強(qiáng)柱弱梁方面，中國要求低于美國和日本；美國WUF-W梁柱節(jié)點(diǎn)的構(gòu)造和設(shè)計(jì)方法與中國、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
