Abstract

Orthotropic steel bridge deck system has a large number of applications in recent years in many countries. Based on the research on the Thicken Edge U rib (TEU), a new fatigue control technology route is put forward in this paper. The conception is that, on the premise of increasing a small amount of material to increase the weld dimension, so as to reduce the fatigue stress range in the weld, until transfer the fatigue control section from the weld to the base material of U rib. Because the fatigue resistance for the base material is much higher than that for the weld, hence, it is expected to completely solve the fatigue cracking problems in the weld of longitudinal ribs connected with steel bridge deck.
