Performance of Cold Formed Steel Shear Wall Panel with OSB Sheathing under lateral load

Cold-Formed Steel Shear Wall Panel (CFS-SWP) is one of a lateral load resisting system in seismic and/or wind area. In this paper, a detailed modeling technique of a Shear Wall Panel (SWP) with OSB sheathing is presented by using finite element, in order to evaluate these performances under lateral load. Material and assembly nonlinearities are introduced in the FE model. The orthotropic material of the OSB sheathing is also considered. The results obtained by the finite element model have been validated with corresponding experimental data. A good arrangement in the nonlinear response has been achieved. Moreover, the performance in terms of shear strength and ultimate displacement has been assessed, confirming that the proposed finite element model can be used to predict the nonlinear behavior and the shear strength of cold formed steel shear wall panels with OSB sheathing.
