ABSTRACT
This study focuses on both tensile and shear strength of self-drilling screws and the tensile strength of thin steel plates connected by the screws at high temperature, to clarify fire resistance performance on the self-drilling screw and the connection, which are widely used for a cold-formed steel structure. Three types of the self-drilling screws, which were manufactured from high strength, martensitic stainless and austenitic stainless steel bars, were respectively used in experiments under constant temperature and increasing load condition. Furthermore, the tensile strength experiments of the screw connections were conducted at the high temperature. The experimental results of the tensile strength of the screw connections approximately agree with those theoretical values proposed in this research. It is expected that the obtained experimental results are useful as databases to establish performance-based fire resistance design for the light-weight steel structure.
