| Improving requirement of energy conservation, environmental protection and economy, low rise dwellings high strength cold-formed thin-walled steel framing structures are applied widely. Differing from traditional beam-columns system, all of vertical load and horizontal load shall be resisted by walls in this structure system. At present, the main behavior of this type wall is studied by test, because of it's complex.The shear resistances of six full-size double boards (steel rib panel + gypsum wall board) of high strength cold-formed steel framing wall are studied in this paper. The experimental phenomena and final failure modes are introduced emphatically in this paper. The test data is processed and the deference of shear resistances of this type wall under monotonic loading without axial compression loading, cyclic loading without axial compression loading and cyclic loading with axial compression loading is compared. Base on the experimental result and failure modes, some suggestions are given for the design of this type walls.Based on the tests, the finite element program ANSYS10.0 is applied to carry out the finite element nonlinear analysis for the shear resistances of high strength cold-formed steel framing wall under monotonic loading without axial compression loading. The FEM models are verified by comparison with the experimental results and calculation results. Then, some parameters which include aspect ratio, column spacing and height of rib of cold-formed steel rib panels, are simulated by using ANSYS. Analysis results of these parameters are important for the design of this type walls in future.
