    Abstract
  • In view of the weakest point of hinged voided slab bridge, namely hinged joint, a kind of voided slab with perforated steel plates at the bottom of hinged joint-to-voided slab interface was put forward, the perforated steel plates were used to change the crack propagating path at the interface, so as to delay the formation of through crack at the hinged joint-to-voided slab interface, and the full-scale model experiment on 8 m-span hinged voided slab was conducted. Based on the experiment and nonlinear finite element (FE) analysis, the result was compared with the experiment result of hinged voided slab with gate-type steel bars at the bottom of interface. Analysis result shows that when the experiment load is 100 kN (1.43 times vehicle load), the lateral crack emerges in the mid-span of voided slab, the integral rigidity of voided slabdecreases, and the stress state of voided slab comes into elastoplastic stage from elastic stage. The test load is applied up to 300 kN (4.29 times vehicle load), no crack is detected at the bottom of hinged joint-to-voided slab interface during the entire loading process. For hinged voided slab with gate-type steel bars at the bottom of hinged joint-to-voided slab interface, the crack extends from the bottom to the top along the interface, and then forms a through crack. However, for the hinged joint-to-voided slab interface with perforated steel plates, after the crack propagates along the interface to the bottom of perforated steel plate, the expansion of the crack needs to bypass the perforated steel plate, so that the joint concrete below the perforated steel plate cracks, and then the crack expands upward along the junction surface above the perforated steel plate until the formation of through crack. The joint cracking load increases from 69 kN (0.99 times vehicle load) for the interface with gate-type steel bars to 314 kN (4.49 times vehicle load), and increases by 3.50 times. The through-crack-formation load increases from 199 kN (2.84 times vehicle load) for the junction surface with gate-type steel bars to 489 kN (6.99 times vehicle load), and increases by 4.51 times. It can be seen that the extension path of crack changes after the perforated steel plate is set at the bottom of junction surface, which slows down the cracking of the junction surface between the voided slab and the hinged joint.
