Abstract
Structural wall sheathings are commonly used in cold-formed thin-walled steel (CFS) shear walls. However, there are few reports on the compressive stress-strain relationships of wall sheathing. To investigate the compressive stress-strain relationships of the wall sheathing, 54 rectangular samples of gypsum wallboard (GWB), oriented strand board (OSB), and fiber cement board (FCB) were designed and manufactured. Compressive loading tests were also conducted, and failure phenomenon, stress, strain, elastic modulus, and Poisson’s ratio of samples were investigated. The results indicate that the failure mode of GWB is a compressive failure at the end of the sample while that of OSB and FCB is an oblique shear failure at the middle of the sample. Finally, a three-stage stress-strain model was proposed. The comparison between the test and calculated curves shows that the proposed model has good accuracy. The results of this paper can be utilized as a reference for engineering applications and theoretical research of CFS shear walls.
