Efficient web profile to resist lateral torsional buckling for steel corrugated web plate I girders is presented in this paper. The cubic equation required to obtain the most efficient corrugated web profile for any given angle and depth of corrugation is derived. The efficient web profile obtained using this cubic equation is verified numerically by analysing standard example problems. The results of all the example problems show that the presented cubic equation can be used to obtain the most efficient trapezoidal web profile for corrugated web plate I girder to resist lateral torsional buckling for any given angle and depth of corrugation.
