The　loading　and　deformation　capacities　of　beam-column　joints　under　large　deformation　have　a　significant　impact　on　the　progressive　collapse　performance　of　prefabricated　concrete　frame　structures.A　static　progressive　collapse　test　was　conducted　on　four　prefabricated　concrete　frame　specimens　with　different　wet　connections　and　one　cast-in-situ　specimen.Mechanical　sleeves,　bent-up　steel　bar　anchorage　and　prestressing　tendon　were　used　as　the　connections　of　beam　reinforcement,　while　rebar　splicing　by　grout-filled　coupling　sleeve　and　rebar　lapping　in　grout-filled　hole　were　used　as　the　connections　of　column　reinforcement.It　is　found　that　all　bottom　reinforcing　bars　in　the　beam　fractured　simultaneously　at　the　same　location　of　one　sleeve　when　the　mechanical　sleeves　were　used,　which　significantly　reduced　the　collapse　resistance　of　the　specimen　under　the　compression　arch　mechanism　and　the　catenary　mechanism.When　the　beam　reinforcement　was　bent　up　and　anchored　in　concrete,　the　mechanical　behavior　and　collapse　resistance　of　the　specimen　were　very　similar　with　those　of　the　cast-in-situ　specimen.The　prestressing　tendon　significantly　improved　the　collapse　resistance　of　the　specimen　under　the　two　mechanisms,　but　local　splitting　failure　of　concrete　in　the　joint　was　induced　by　the　concentrated　load　transferred　from　the　prestressed　anchors　under　the　ultimate　deformation.The　rebar　splicing　by　grout-filled　coupling　sleeve　and　the　rebar　lapping　in　grout-filled　hole　of　the　column　steel　bars　were　capable　to　withstand　the　horizontal　shear　force　under　large　deformation　in　progressive　collapse,　but　shear-slip　of　the　column　joint　grouting　layer　was　found　when　exposed　to　the　significant　horizontal　shear　force,　which　in　turn　weakened　the　constraint　of　the　column　to　the　beam.When　the　collapse-resisting　mechanism　was　transformed　from　the　compression　arch　mechanism　to　the　catenary　mechanism,　the　axial　compressive　force　of　the　compressive　arch　mechanism　negatively　contributed　to　the　collapse　resistance　of　the　specimen.The　contribution　of　axial　force　to　collapse　resistance　of　the　specimens　connected　by　mechanical　sleeves　and　prestressing　tendon　were　respectively　higher　and　lower　than　that　of　the　cast-in-situ　concrete　specimen.　©　2019,　Editorial　Office　of　China　Civil　Engineering　Journal.　All　right　reserved.
