The steel plate girder with the corrugated web is widely used in many applications because it has many advantages. It has a high resistance against lateral-torsional buckling compared with another flat web girder with the same steel weight. The design method for calculating the lateral-torsional buckling strength of corrugated web girders is not provided in the current standards and specifications. This paper focuses on the strength of corrugated web girders against lateral-torsional buckling and presents the theoretical and finite element analysis to study the behavior of this type of girders. The Nonlinear finite element analysis is carried out using ANSYS. The influence of various parameters (web thickness, web height, corrugation angle, corrugation width, and corrugation shape) is considered in this study. Where there are a few approaches such as Linder, Moon, and Zhang that explain how to determine the warping constants of corrugated web beams therefore, the applicability of these approaches is evaluated in this study. It is found that the formulas of Moon and Zhang are more accurate than the Linder formula except in the case of beams with a ratio between web height and flange width equal or less than 2.0. The applicability of using the Euro-code equations of the lateral-torsional buckling moment for plate girders with flat webs in cases of girders with corrugated webs is studied. It is concluded that the Euro-code equations can be used for corrugated web girders with a good agreement after using Moon's or Zhang's formula to calculate the warping constant.

“…Kazemi et.al [4] performed analytical study to determine lateral torsional buckling moment for simply supported girders with corrugated webs subjected to end moments and they found that the lateral torsional buckling moment of girders increased up to 40% by using corrugation profiles of the web. Fatimah De'nan [5] performed analytical study to investigate the effect of web corrugation angle for triangular web on the bending behavior in minor and major axes and compare results with flat girders and they concluded that the value of moment of inertia about major axis I X for the corrugated web is in a range from 0.754 to 0.818 times of that for flat web. The value of moment of inertia about minor axis I y for corrugated web is in a range from 1.523 to 1.686 times of that for flat web.…”

This paper presents the results of the theoretical and finite element analyses of the lateral torsional buckling behavior of I-girders with corrugated webs with and without openings. Previous studies on the behavior of the I-girders with corrugated webs are first discussed. Then, the elastic lateral torsional buckling moment M cr of all analayzed girders are determined numerically by using Euro-code equations by the three methods suggested by Lindner, Zhang et al. and Moon et al. Finally, the effect of different parameters such as (web thickness, web height, flange thickness, flange width and corrugation shape) on lateral torsional buckling resistance using finite element analysis are studied and verify the results with Euro-code equations.
