RESEARCH STATUS ON FATIGUE BEHAVIOR OF STEEL-CONCRETE COMPOSITE BEAMS

The fatigue behaviour of the steel-concrete composite beam has been paid attention in recent years. But there is still not much research on the fatigue behaviour of the steel-concrete composite beam in China. In order to provide reference and basis for research on fatigue behaviour and design of the composite beam, the review of available literatures is made including the experimental study, calculation method and requirements in Code. The fatigue failure models and influence factors are concluded. Based on a large number of fatigue experimental data of studs, design rules in various Codes are analyzed and summarized. The research work by this paper is useful for the further experimental study, practical design and Code amending.
