Abstract

This paper presents results of a numerical study on the shear strength of cold-formed steel channels with solid and slotted webs. The effects of four different boundary conditions—test setup, realistic, and simply supported with free and restrained ends—on the elastic shear buckling load and the ultimate shear strength were considered. The study was performed on finite element models developed in ANSYS and validated against test data. The obtained results showed that the elastic shear buckling loads and the ultimate shear strengths of the slotted channels are more sensitive to the boundary conditions when compared with the solid channels. The simply supported boundary conditions can reasonably well simulate the test setup boundary conditions of the solid channels but not the slotted channels. The realistic boundary conditions cannot be accurately simulated by the simply supported boundary conditions for the solid and slotted channels.

Numerical Simulations of Solid and Slotted Cold-Formed Steel Channels with Different Boundary Conditions in Shear

This paper presents results of a numerical study on the shear strength of cold-formed steel channels with solid and slotted webs. The effects of four different boundary conditions—test setup, realistic, and simply supported with free and restrained ends—on the elastic shear buckling load and the ultimate shear strength were considered. The study was performed on finite element models developed in ANSYS and validated against test data. The obtained results showed that the elastic shear buckling loads and the ultimate shear strengths of the slotted channels are more sensitive to the boundary conditions when compared with the solid channels. The simply supported boundary conditions can reasonably well simulate the test setup boundary conditions of the solid channels but not the slotted channels. The realistic boundary conditions cannot be accurately simulated by the simply supported boundary conditions for the solid and slotted channels.
