    Abstract
  • Focused on the full-depth hinged joint with gate-type steel rebars at the bottom of junction surface between voided slab and hinged joint, a full-scale model with one span of 8 m according to the standard drawings of hinged voided slab bridge issued by Ministry of Transportation in 2007 was designed. With experiment and nonlinear finite element method, the failure modes of hinged voided slab under vehicle load were studied, including failure type, failure position and cracking load. Analysis result indicates that the nonlinear finite element model can properly simulate the mechanical properties of hinged voided slab under vehicle load by comparing with experimental result. The vertical relative slip is regarded as the index of cohesion failure of junction surface in three directions of bonding-slip relationship. Under vehicle load, the weakest position is the junction surface between voided slab and hinged joint. The surface starts to crack when the load reaches 69 kN(0.99 times of vehicle load), but the crack appears at the middle of voided slab when the load reaches 85 kN(1.21 times of vehicle load). Compared with the experiment on hinged voided slab with full-depth joint without gate-type steel rebars, when the gate-type steel rebars are laid at the bottom of junction surface, the cracking load increases unobvious, but the load that through cracks appear along the intersection between slab and hinged joint increases from 140 kN(2.00 times of vehicle load)to 199 kN(2.84 times of vehicle load), and through crack along longitudinal direction can be prevented.
