Assembly　light　steel　tube　frame　with　recycled　concrete-thin　wall　was　proposed,　which　was　suited　for　lower　or　multilayer　floors　farmhouse.　Assembly　frame　was　assembled　by　recycled　concrete　filled　light　steel　tube　beams　and　columns,　and　light　wall　adopted　single　row　of　steel　bars　and　recycled　concrete.　Frames　and　walls　were　connected　by　bolts.　The　frame　bears　the　vertical　load　and　resists　the　horizontal　load　with　walls　together.　Pseudo-static　tests　on　4　assembly　light　steel　frame-thin　wall　and　1　single　frame　were　conducted　to　study　the　influence　of　reinforcement　spacing　and　the　wall　thickness　on　the　joint　work　performance　of　frames　and　walls.　Failure　modes,　hysteresis　property,　load-carrying　capacity,　ductility,　stiffness　and　energy　dissipation　capacity　of　specimens　with　different　bar　spacing　and　wall　thickness　were　analyzed.　The　results　indicate　that　light　steel　frame-thin　wall　distinctly　has　two　seismic　defensive　lines　and　works　together　well.　The　failure　modes　of　walls　are　the　shear　failure　and　the　frame　are　the　axial-flexural　failure,　respectively,　which　indicate　that　the　assemble　components　are　safe　and　reliable　and　the　structure　has　adequate　ductility.　Reducing　spacing　of　bars　or　increasing　thickness　of　the　wall　can　improve　ductility　and　dissipation　capacity　of　specimens.　©　2017,　Editorial　Board　of　Journal　of　Harbin　Institute　of　Technology.　All　right　reserved.
