Assembly　voided　slab　bridge　is　widely　been　used　in　China,　there　are　many　advantages　could　be　found　on　this　kind　of　bridge.　However　the　hinged　joint　is　the　weakest　part　of　the　structure.　Many　drawings　of　typical　Chinese　assembly　voided　slab　bridge　were　collected,　some　rules　were　gained　by　statistical　analysis.　A　field　inspection　of　an　expressway　in　China　was　performed　in　2012,　assembly　voided　slab　bridge　takes　up　a　large　proportion　of　bridges　in　this　expressway.　Some　rules　of　distress　of　assembly　voided　slab　bridge　were　also　acquired　by　statistical　analysis.　Based　on　the　finite　element　analysis　and　experimental　results　that　had　been　finished　before,　a　new　kind　of　hinged　joint　was　put　forward.　©　2014　Taylor　&　Francis　Group.
