Abstract
The purpose of current research is to evaluate the shear behavior of I-section beams made of double C-shaped of cold formed steel, considering the opening in web for the passage of mechanical and electrical infrastructure. Due to the weak shear resistance caused by hole in web, the shear capacity and bearing capacity of the beam section is greatly reduced. The size, shape and arrangement holes are effective in the bearing capacity and final strength of the beam section. using the finite element method, the steel beam with length of 1000 mm has been investigated under the effect of a concentrated load in the middle of the span. variable parameters are sheet thickness, dimensions hole, shape hole, hole distances from the support, and the presence of edge in the section wing, which has been subjected to nonlinear static analysis of an additional load concentrated in middle of the beam. For checking the accuracy, the analysis results, the shear strength of the analytical models compared with the shear strength calculated from direct strength method (DSM) of the AISI. The results showed that in sections with equivalent areas and different hole shapes, with increase of hole depth, the final capacity decreases in rectangular, circular and square holes, respectively; The section with rectangular hole has increase of about 4% compared to circular hole, and the section with circular hole has increase of 7% compared to square hole. by increasing the holes distance the performance of the beam is improved and the maximum shear strength of the sections obtained by the finite element method increases 4% and 6%, and with the increase in sheet thickness (despite the increase in depth and length hole), from 2 to 2.5 mm and 2.5 to 3 mm, the shear capacity increases about 25% to 30% and 20%, respectively.
