Abstract : The main purpose of using corrugation is to increase the shear strength of the web, hence no stiffeners are required for the same. This helps in reducing the material and fabrication cost. For a simply supported beam, the shear force is less in the middle portion of the span. Therefore, the web is kept plain in the middle portion and corrugations are provided for the remaining portion. Hence, it is called as semi-corrugated web. In this paper, various models of the web are analysed in ABAQUS. The shear stress of the plain-webbed beam and that of semi-corrugated webbed beam is compared for the same loading. The behaviour of the semi-corrugated web is then observed by changing the height of the web. The optimum depth of corrugation is found out by changing the flange width and the depth of corrugation.
