| Abstract: | In this paper,the ultimate strength of beams with trapezoidally corrugated webs under shear loading has been studied using a nonlinear finite element method.Large deflection of plate elements and elastic perfectly plastic model of materials are involved in the analysis,and the effect of initial imperfection of webs is considered.The comparison of behavior between I beams with trapezoidally corrugated webs and flat webs has been carried out.It is found that the shear carrying capacity of the beam with corrugated web is much higher than that of the beam with common flat web. |
