Abstract
Prefabricated lightweight steel composite structures are characterized by efficient load-bearing, seismic energy-saving, and eco-friendly attributes, primarily used in low-rise and multi-story buildings, adapting to the development of modern architectural industrialization. This review covers the development process, system composition, and current research status of structural seismic performance for typical prefabricated lightweight steel composite structures, including prefabricated cold-formed thin-walled steel structures, prefabricated lightweight steel-lightweight concrete structures, and prefabricated lightweight steel composite frames - lightweight steel composite shear wall structures. The analysis includes the technical features, standard systems, and current environmental applications of the aforementioned structures, raises several issues in the research of prefabricated lightweight steel composite structures, and provides a research outlook for the future development direction of prefabricated lightweight steel composite structures.
