ABSTRACT

In this paper, experiment and finite element (FE) method are adopted to study the shear resistance of cold-formed steel stud walls in low-rise residential structures. Firstly, the shear resistance of the cold-formed steel stud assembled walls under monotonic loading is tested. The test models, including walls with single-sided gypsum sheathing, walls with single-sided oriented strand board sheathing, and walls with gypsum sheathing on the back and oriented strand board on the front, are made in full scale of engineering project. The test apparatus, test method, and the failure process of the specimens are introduced in detail. Then, based on the ANSYS program, the FE model of the cold-formed steel stud walls considering geometric large deformation and materials nonlinearity is presented. The walls are simulated as shell elements. The studs as well as the tracks are simply connected, and the screws connecting the sheathings to the frame are modeled by coupling methods. The validity of the FE method is verified, and then a series of parametric analyses are carried out. All this work will provide guidance in theory for practical application of this kind of wall.
