Abstract：

The　structural　system　of　the　resilient　prestressed　steel　frame　with　intermediate　column　containing　friction　damper　and　the　typical　details　of　the　intermediate　column　containing　friction　dissipation　damper　were　put　forward　for　researching　the　resilient　capacity　to　large-span　prestressed　steel　structures.　An　eight-story　prototype　structure　was　designed　and　a　static　pushover　test　of　the　first　two-story　plane　frame　was　conducted.　The　numerical　simulation　was　also　carried　out　by　using　the　software　ABAQUS.　The　results　show　that,　the　intermediate　column　containing　friction　dampers　increases　not　only　the　structural　rigidity　but　also　the　energy　dissipation　capacity.　The　main　structure　still　remains　elastic　except　the　reinforcing　plate　of　beam　flange　and　web　plate　of　column　foot.　The　story　shear　force-displacement　hysteresis　model　of　the　two-story　plane　steel　frame　was　acquired　by　the　pushover　test,　and　the　hysteresis　models　of　story　1　and　story　2　exhibited　shuttle　shape　and　arc　shape　respectively,　which　is　the　basis　of　further　study　on　the　mechanical　performance　of　the　structural　system.　The　loss　of　prestressing　steel　strand　force　is　very　little　after　the　test　and　can　provide　an　excellent　self-centering　mechanism　and　capacity　of　resilient　structure　function.　©　2016,　Science　Press.　All　right　reserved.
