The　influence　of　four　different　types　of　assembly　beam-column　joints　and　steel　tubes　with　or　without　recycled　concrete　on　the　seismic　performance　of　fabricated　light　weight　concrete-filled　steel　tube　(CFST)　frames　were　investigated　in　the　first　part　of　this　paper.　The　results　showed　that　the　CFST　frame　with　a　double-L-stiffened　connection　joint　showed　high　strength　and　good　seismic　behavior.　The　bearing　capacity　of　the　frame　was　given　by　the　simple　plastic　analysis　method,　and　the　calculation　error　compared　to　the　test　result　was　less　than　10%.　As　the　main　focus　of　this　paper,　the　light　weight　CFST　frame-fabricated　single　row　reinforced　shear　wall　structures　were　proposed　in　the　second　part　of　this　paper　on　the　preliminary　study　of　the　light　weight　CFST　frame.　Four　specimens　with　different　wall　thicknesses　and　different　reinforcement　spacing　were　tested　under　low-reversed　cyclic　loading.　The　experimental　results　indicated　that　the　proposed　fabricated　method　ensured　that　the　wall　cooperated　well　with　the　CF　ST　frame,　and　the　structure　had　two　obvious　seismic　fortification　lines.　The　fabricated　shear　wall　was　the　first　seismic　fortification　line　subjected　to　shear　failure,　and　the　CFST　frame　was　the　second　seismic　fortification　line　subjected　to　flexural　failure.　The　assembly　of　the　shear　wall　substantially　improved　the　structural　strength　of　the　single　CFST　frame,　while　the　CFST　frame　improved　the　structural　seismic　collapse　resistance.　The　superposition　calculation　of　the　bearing　capacity　of　the　CFST　frame　and　fabricated　shear　wall　was　used　to　estimate　the　bearing　capacity　of　the　light　weight　CFST　frame-fabricated　single　row　reinforced　shear　wall　structure.　The　calculation　results　showed　good　agreement　with　the　experimental　results.
