Behavior of screwed connections in stainless steel frame shear walls sheathed with ply-bamboo panels

The behavior of sheeting connections is important in thin-walled structures, especially when diaphragm skin action is considered for these structures. This paper presents an experimental study on the monotonic and cyclic loading behavior of self-drilling screw connections in stainless steel frame shear walls sheathed with ply-bamboo panels. A total of 46 screwed connection specimens were tested to determine the effects of loading rate, end distance of screws and screw features. The results observed in this study have presented the failure modes and the effects of different factors. It is shown that, the shear behavior of screw connections is little affected by loading rate; both strength and deformation increase with the end distance increasing in the tested range; the shear behavior of phosphating self-drilling screws is superior to stainless steel self-drilling screws.
