Corrugated steel webs are only able to resist shear force because of the accordion effect. The shear force in the web can cause three different buckling modes: local, global, and interactive shear buckling. While several researchers have been investigated the shear buckling behavior of corrugated webs, the shear buckling behavior of the corrugated webs has not yet been clearly explained. This paper presents shear buckling design of trapezoidally corrugated steel webs. Considering the profiles of existing bridges with corrugated steel webs, global and interactive shear buckling coefficient, and shear buckling parameter are derived. Then, shear design criterion for corrugated steel webs are suggested. The proposed design criterion is compared with the test results and those of previous researchers for verification purpose. From the result of comparative study, it is found that the proposed shear strengths provide good predictions for the shear strength of the corrugated steel webs.
