Abstract

Cold-formed thin-walled steel was used as bearing capacity structures of multi-story and low story dwellings, in which oriented strand board(OSB) was used as wall board and floor board. The composite floor is made of cold-formed thin-walled steel multi-ribbed beam and OSB. It´s bearing capacity performance is closely related to shearing strength, spacing, and tightness of self-threading screw. In this paper, elastic analysis on interaction of cold-formed thin-walled “C” steel beam and OSB was carried out, and the bearing capacity calculated formulas of composite floor was obtained, considering the influence of sliding between steel beam and OSB. And the reduction coefficient of floor flexural rigidity related to screw was determined also.
