［摘要］介绍了标准JGJ99—98，GB50011—2001，CECS160:2004，EC8，ANSI/AISC341—02和日本极限状态设计指南中关于钢结构“强节点弱构件”的抗震设计方法，包括梁柱刚性连接、支撑与框架连接和连接部分设计抗力的计算方法。通过归一化后的Φ值比较，评价了各标准的设计方法。分析表明，按JGJ99—98，GB50011—2001设计的节点最弱，按CECS160:2004设计的最强，按ANSI/AISC341—02设计的略弱于CECS160:2004。考虑到大震下要求节点不坏，GB50011—2001和JGJ99—98中有关节点部分的设计有待进一步研究。

Abstract:The aseismic design methods about the “strong connection-weak connected member"concept in steel structures,including the beam-to-column rigid connections，bracing connections and the calculation methods for design resistance of connections，are briefly introduced according to JGJ99—98，GB50011—2001，CECS160:2004，EC8，ANSI/AISC341—02，and recommendation for limit state design of steel structures of Japan. Based on the comparison of normalized Φ values for the different codes, the design methods of these codes are evaluated. The analysis shows that, the connections are demanded to the weakest for the JGJ99—98 and GB50011—2001 codes and the strongest for CECS160:2004 codes, which slightly greater than that in ANSI/AISC341—02 code. Considering that the connections are demanded to not failure under strong earthquake, the connections design method for JGJ99—98 and GB50011—2001 codes needs further research.
