Abstract

Using an opportunity of reconstruction of a assemble PC hollow slab bridge, the mechanical behaviour of a hinged joint and hollow slab under vehicle loads are discussed is this paper, such as the cracking load and load transmitting performance. The results show that the cracks occurred in the bottom of the beam when the offset load reached 365kN (1.3 times of a vehicle load), and concrete of roof tend to be crushed with load increasing to 500kN (2.0 times of a vehicle load). During the whole loading process, the shallow hinge joint structure has not been cracked, which showed good shear transfer performance. In addition, based on the principle of solving the internal force of hinged joint under the vehicle load, the theoretical and experimental results show that shear hinge joint has strong bearing capacity, the test can reflect that the failure mode of hinge joint in the assembled hollow slab is not caused by shear stress.
