EXPERIMENTAL STUDY ON LATERAL RESISTANCE BEHAVIOR OF LIGHT STEEL SKELETON-STRUCTURAL SHEET COMPOSITE WALL

Lateral resistance experiments on eight composit walls of light steel skeleton-wood or bamboo sheet and two ones of no sheet,for comparison,were conducted.The experimental result indicates that light steel skeleton-structural sheet composite walls which is adopted generally in low-rise housing system of North American have high resistant capacity of lateral load.The composite walls show excellent energy absorption property subjected to lateral load,which is due to the special connection of structural sheet and steel skeleton by screws.Based on tests and analyses,the conseption of composite wall which is composed of light steel skeleton and structural sheet is put forward,which generalizes the mechanical behavior of this kind of wall in an all-around way.It is a beneficial exploration for the research and development of the new-type light weight steel structure system.
