【Abstract】 The fatigue damage of a steel member is one of the main failure modes of the steel structures.Through the fatigue tests and the analysis of “K” weld of steel a member with tension-tension stress.It is concluded that sticking the CFRP on the weld of steel member can reduce the stress concentration of the weld,which improves the fatigue performance,such as the fatigue life of steel member evidently,which shows high engineering values of steel structural weld reinforced with CFRP.更多还原
