Abstract
This paper presents the test results of corrugated web girders under pure bending. Four different trapezoidal corrugation configurations, including a flat web, were used. All the girders tested failed due to local buckling of the compression flange at near the mid-section. The test results of bending behavior and ultimate strength were compared with the numerical analysis using the finite-element program DIANA. It was confirmed that the contribution of the corrugated web to the bending capacity is negligible and the ultimate strength can be estimated conservatively from the yield moment for only two flange sections. A predicting method of the ultimate strength considering local flange buckling was also proposed based on the parametric analysis of corrugated web girders.
