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.
