Abstract

Abstract

The fatigue performance of composite beams in bridge structure and crane beam has attracted researchers' attention. The fatigue test of composite beam with laminated slabs under constant amplitude load was carried out. According to the fatigue test results,the data of fatigue life of composite beams with the same fatigue failure mode was fitted according to double logarithmic model. and the S-N curve of composite beams with stud shear failure was obtained. The results were very close to those of ECCS,which could be used to design bridge with the composite beam. Both of the composite beam with laminated plate and with cast-in-site plate showed almost the same fatigue performance.
