Abstract:In order to study the fatigue failure behavior and fatigue strength of orthotropic steel deck of urban rail transit steel bridge, a full-scale test model of orthotropic steel deck was established based on the main span beam of a cable-stayed bridge of urban rail transit. During the test, the stress values and the cracking condition of the structure was observed to evaluate the fatigue strength. The results show that there is no crack during 2 million external load cycles, the main tensile stress values of each… Show more
