STRENGTH OF CONCRETE BRIDGE DECKS
Behavior of two reduced-scale concrete bridge decks subjected to simulated wheel loads was evaluated in a series of tests. One slab was reinforced in accordance with AASHTO requirements; the other had three areas with varying amounts of isotropic reinforcement. Results show that with either reinforcement pattern, service-load bending moments are from 40 to 65 percent of those predicted by flexural theory. These results were confirmed for the conventionally reinforced slab by service-load tests on an in-service full-scale bridge deck. Failures were by punching shear rather than flexure and occurred at loads at least six times larger than design.
