Abstract:Theoretical and technical development of cold-formed steel structures and their engineering application in China have been briefly reviewed and discussed, including typical sections and corresponding study on their properties, design theories and methods of cold-formed steel members, structural systems and engineering practice using cold-formed steel, seismic, fire and wind issues of cold-formed steel structures, development of technical codes regarding cold-formed steel structures, etc. Furthermore, existing problems and possible development direction for using cold-formed steel structures were discussed, which may be helpful for further domestic research and engineering practice.

Keywords:cold-formed steel structure; theoretical and technical development; engineering practice; technical code
