Abstract:
4 full-scale cold-formed thin-walled steel composite walls were tested under monotonic loading and the shear resistance behaviors of specimens were obtained. The finite element model involving material nonlinearity and geometric nonlinearity was established to simulate the test models. Then the numerical analysis results on shear resistance behaviors of composite walls with different opening sizes were carried out by using finite element method. Meanwhile, the design methods for calculating shear capacities of composite walls with opening were proposed. The results show that the main destruction of composite walls with opening take place around the opening. The sheathing is crushed and torn along the direction of 45 degree around the door or window opening. When all specimens have the same configuration, the shear capacities and lateral stiffness of composite walls with opening decrease with the increase of opening rates. The results calculated by recommended design method in the paper agree well with the ANSYS results, so it can be served as reference for practical engineering design.
