Abstract

Abstract

Slab-rib form is one of the important factors that affects the bending fatigue behavior of precast prestressed concrete composite slab.In order to study the effect of slab-rib form on bending fatigue behavior of composite slab, a comparative test of bending fatigue of one T-shaped ribbed plate composite plate specimen and four rectangular ribbed plate composite plate specimens was carried out. The parameters include slab-rib form and fatigue load amplitude. The failure mode, crack distribution, load-deflection curve, load-strain relation curve were obtained. The influence of slab-rib form and fatigue load amplitude on fatigue damage degree of composite slab was analyzed. The results showed that the fatigue bending stiffness of the plate decreased obviously and the fatigue damage increased obviously with the increase of fatigue load amplitude. However, the fatigue damage of superimposed surface was relatively small, which indicated that the existence of superimposed surface would not affect the mechanical propcrties of composite slab. The bending fatigue behaviors of rectangular ribbed composite slab was the same as that of T-shaped ribbed plate.
