To　solve　the　disease　of　hinged　joint　in　the　existed　prefabricated　voided　slab　bridges,　a　new　type　of　prefabricated　inverted　T-shape　voided　slab　bridge　was　presented.　The　full-scale　model　experiment　and　the　nonlinear　finite　element　analysis　on　the　inverted　T-shape　voided　slab　bridge　with　8　m　span　were　conducted.　The　stress,　deflection　and　crack　distributions　of　each　component　of　inverted　T-shape　voided　slab　bridge　subjected　to　the　vehicle　load　were　analyzed.　The　force　mechanism　and　failure　mode　of　inverted　T-shape　voided　slab　bridge　were　obtained.　The　mechanical　behaviors　of　inverted　T-shape　voided　slab　bridge　and　voided　slab　bridge　with　gate-type　steel　bars　were　compared.　The　effectiveness　of　inverted　T-shape　voided　slab　solving　the　problem　of　cracking　in　hinged　joint　was　verified.　Research　result　shows　that　the　failure　process　of　inverted　T-shape　voided　slab　bridge　can　be　divided　into　the　elastic　stage,　cracking　stage　of　voided　slab,　cracking　stage　of　concrete　in　the　field-cast　structure　layer,　and　yielding　stage　of　tensile　steel　bars　and　steel　plates.　The　inverted　T-shape　voided　slab　bridge　have　a　good　overall　mechanical　property,　its　ultimate　capacity　is　1.4　times　of　that　of　voided　slab　bridge　with　gate-type　steel　bars.　The　concrete　in　the　tensile　area　above　the　Ω-shape　steel　plate　is　a　weak　part,　for　its　tensile　stress　firstly　reaching　the　limit　3.17　MPa.　Due　to　the　existences　of　Ω-shape　and　L-shape　steel　plates,　when　the　concrete　in　the　field-cast　structure　layer　cracks,　the　normal　and　tangential　bonding　stresses　of　each　junction　surface　as　high　as　the　field-cast　structure　layer　will　not　exceed　their　limit　2.30　and　0.29　MPa,　respectively,　avoiding　the　bonding　failure　on　the　junction　surface.　Comparing　with　the　mechanical　property　of　voided　slab　bridge　with　gate-type　steel　bars,　the　inverted　T-shape　voided　slab　structure　does　not　reduce　the　cracking　load　of　voided　slab,　and　the　junction　surface　between　the　old　and　new　concretes　cracks　after　the　cracking　of　voided　slab.　It　can　fundamentally　solve　the　problem　that　the　hinged　joint　cracks　before　the　cracking　of　voided　slab　under　the　vehicle　load.　2　tabs,　30　figs,　30　refs.　©　2019,　Editorial　Department　of　Journal　of　Traffic　and　Transportation　Engineering.　All　right　reserved.
