Set　perforated　steel　plate　in　the　original　concrete　hinge　joints,rebar　penetrate　the　hole　similar　to　the　method　of　mechanical　hinge,so　as　to　solve　the　safety　problem　of　concrete　hinge　joints　after　single　plate　loading,and　the　push-out　test　and　numerical　simulation　are　carried　out　for　the　shear　performance　of　the　hinge　joint　structure.In　view　of　the　phenomenon　of　the　damage　of　the　concrete　hollow　slab　concrete　hinge　joints,the　test　is　carried　out　aiming　at　the　hinge　joint　structure.The　failure　mechanism　of　the　joint　is　analyzed　by　observing　the　failure　process　and　failure　mode.Finite　element　method　is　used　for　the　numerical　simulation　of　the　joint　test　of　the　perforated　plate　joints.First　stage,when　the　experimental　load　started　acting　on　the　specimen,there　was　no　slip　on　interface　because　of　static　friction;　second　stage,with　the　increasing　of　load,the　crack　began　to　develop　in　the　interior　of　the　interface　and　gradually　form　a　larger　cracks,perforated　steel　plate,rebar,concrete　mortise　and　joint　surface　bear　external　load　together;　three　stage,crack　penetrate　the　hinge　joint　interface,the　interface　shear　was　entirely　bored　by　perforated　steel　plate,reinforced　concrete　mortise,until　completely　destroyed.The　validity　of　the　numerical　simulation　method　is　verified　by　the　load-slip　curve　and　the　failure　mode　of　the　specimen,which　can　provide　a　basis　for　further　study　on　the　shear　performance　and　calculation　method　of　the　new　structure.　©　2017,　Editorial　Department　of　Journal　of　SJZU.　All　right　reserved.
