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.　©　2015,　Chang＇an　University.　All　right　reserved.
