In　order　to　meet　the　needs　of　the　development　of　low-rise　assembly　structure　in　rural　areas,　a　fabricated　light-weight　steel　frame-composite　light　wall　structure　is　proposed　in　this　paper.　The　light-weight　steel　frames　are　used　to　bear　the　vertical　loads.　The　single-row-reinforced　recycled　concrete　wall-boards　are　used　as　lateral　members　to　resist　most　of　the　horizontal　earthquake　loads.　The　wall-board,　EPS　(Expanded　Polystyrene)　insulation　modules,　and　fly　ash　blocks　form　the　thermally　insulated　wall.　Four　fabricated　lightweight　steel　frame-composite　light　wall　structures　and　one　light-weight　steel　frame　(FRA)　structure　were　tested　under　the　low　cyclic　loads.　The　influence　of　wall　reinforcement　spacing　and　structural　form　(be　it　fly　ash　block　or　not)　on　the　seismic　performance　of　this　new　structure　was　analysed　and　the　damage　process　of　the　specimen　was　simulated　using　the　ABAQUS®　software.　The　results　show　that　the　light　steel　frames　and　the　single-row-reinforced　recycled　concrete　wall-board　can　work　well　together.　Furthermore,　the　structure　has　two　clear　seismic　lines.　Due　to　the　use　of　EPS　insulation　modules　and　fly　ash　blocks,　the　structure　has　good　anti-seismic　and　thermal　insulation　abilities.　Reducing　the　spacing　of　bars　or　compositing　fly　ash　blocks　can　significantly　improve　the　seismic　performance　of　the　structure.　The　finite　element　method　(FEM)　calculations　agreed　well　with　the　experimental　results,　which　validates　the　proposed　model.　©　2019　Czech　Technical　University.　All　rights　reserved.
