Experimental Study on the Development Regularity of Slab Concrete Cracks under Fatigue Loads

Abstract:

As for the study on the development regularity of slab concrete cracks under the fatigue loads with amplitude of certain values, two groups of reinforced concrete slab bridge specimen were made. The fatigue test was carried out on one group of specimen, and the corresponding static load test was carried out on another group of specimen, the experimental study on the development regularity of concrete cracks at bottom of slab were carried out. The results of the study shown that, under the fatigue loads at a certain amplitude, the development trend of cracks caused by loading at the bottom of slabs changed more under fatigue loads. The reasons caused the changes of development regularity of concrete cracks were analyzed. The experimental results has the vital significance of further research on the development regularity of concrete bridges under the action of fatigue loads.
