The　industrialized　innovative　buildings　are　promoted　vigorously　in　China,　and　a　main　approach　of　industrialization　is　to　innovate　and　develop　prefabricated　buildings.　Prefabricated　lightweight　steel　composite　structure　has　the　advantages　of　better　mechanical　property,　better　seismic　behavior,　better　energy-saving　and　environment-friendly　properties.　The　prefabricated　lightweight　steel　composite　structure　is　mainly　used　in　low-rise　and　multi-story　buildings,　which　adapts　to　the　development　of　innovative　building　industrialization.　The　research　progress,　system　configuration　and　seismic　behavior　of　several　typical　prefabricated　lightweight　steel　composite　structures　are　summarized.　The　cold-formed　steel　framing　structure,　lightweight　steel　and　lightweight　concrete　structure,　prefabricated　floor-by-floor　assembled　steel　braced　structure,　and　the　prefabricated　lightweight　steel　frame-composite　wall　structure　are　introduced.　The　technical　characteristics,　standards,　construction　technology,　and　engineering　practice　of　those　structures　are　analyzed.　The　problems　and　development　of　prefabricated　lightweight　steel　composite　structures　are　presented,　and　the　future　development　direction　of　prefabricated　lightweight　steel　composite　structure　is　studied　and　prospected.　©　2021,　Progress　in　Steel　Buiding　Structures.　All　right　reserved.
