Abstract
Although steel girders have been used for many years, new generation of optimized steel girders is developed by the advances in structural and fabrication technology. Girders with corrugated webs are used as an efficient alternative to conventional girders with flat stiffened webs. It was also found that, the corrugated girders had a reduction in weight when compared with the beam with flat web. Advantages Economical design of steel girders normally requires thin webs. The use of corrugated webs is a possible way of achieving adequate out-of-plane stiffness without using stiffeners. The corrugated webs are the main elements for bearing the shear forces In this research a comparison between flat web and corrugated web I-beams and the effect of different web corrugation are presented using structural analysis program (SAP2000).
