Abstract：

A　series　Anti-slipping　tests　on　steel　pipe　joints　with　swivel　coupler　were　carried　out　in　this　paper.　Sixteen　specimens　after　turnover　loaded,　were　tested　to　investigate　the　influence　of　variations　in　the　Fastener　tightening　torque　(Tr,　from　20　to　40N·m),　fastener　turnover　frequency　(N,　from　10　to　50)　and　turnover　loading　amplitude　(P,　from　4.0　to　8.0kN)　on　the　anti-slipping　performance　of　steel　pipe　joints　with　swivel　coupler.　The　experimental　results　showed　that,　the　anti-slipping　ultimate　strength　and　stiffness　of　specimens　were　increased　first　and　then　decreased　with　increasing　Tr　or　N,　and　decreased　with　increasing　P.　The　swivel　coupler　turnover　should　not　exceed　the　number　of　20,　and　the　force　of　diagonal　bracing　bearing　should　less　than　6　kN.　©　(2013)　Trans　Tech　Publications,　Switzerland.
