Bending tests on the steel grid composite deck with the prefabricated joint were conducted for the evaluation of bending and failure behavior. The joint of deck is composed of concrete shear key and high-tension bolts. Test results show that deck with the joint has a larger load bearing capacity than continuous deck without joint, and the both decks have almost the same punching shear strength.
