【Abstract】 Based on the characteristics of service condition and failure mode of the steel used in buildings in earthquake areas under alternative earthquake load, the effects of toughness of steel on the seismic performance of buildings in earthquake areas were analyzed. The development abroad and the current situation at home were described. The suggestions for avoiding low temperature and low stress brittle fracture of steel in buildings in earthquake areas were proposed.更多还原
