Abstract
The corrugated web girders had a wide applications because of its many favourable properties. Such as there is no need for intermediate stiffeners to avoid local buckling of the web and the reduction in web to produce by this technique. This study is an experimental investigation of flexural behaviour of I-section steel beams with corrugated webs and flat flange. The study involved testing six groups of steel beams. Each group consisted of two identical specimens and the average result was taken for compression. The first two groups consisted of standard and built-up I-section beams which served as a control beams. The other four groups content a corrugated web beams with different corrugation profiles (trapezoidal, rectangular, sinusoidal and zigzag). The experimental results showed that flexural contribution of the web does not exceed 7-11% from the total beam bending capacity for all configurations types. The rectangular corrugated web had the higher bending capacity and mid-span deflection among all the corrugation types.
