EXPERIMENTAL RESEARCH ON PERFORMANCE OF LIGHTWEIGHT ENERGY-SAVING COMPOSITE WALL ON THE VERTICAL AND LATERAL LOADS

摘要

To overcome the shortcomings of assembly lightweight steel structure residential system in our country. A new type of lightweight energy-saving composite wall is proposed, which is composed by light-gauge shaped steel and thin panel. In order to investigate the load-bearing behaviour and failure mode of the composite wall, 4 wall specimens in full ratio were designed and manufactured. The experiment study is carried out under lateral loading and vertical loading. The results show that the self-drilling screw integrate the light-gauge shaped steel and thin panel to bear loads. The decrease of self-drilling screw spacing can effectively enhance the loadbearing capacity of the composite wall, and the best choice of the self-drilling screw pitch is 150 mm. The composite wall has good bearing and deformation capacity, and it is suitable for applying to light weight steel residential system in our country.
