Since experimental studies of the characteristics of ultimate shear strength in the structural system of U-shaped steel girders, generally called open cross-sectional box girders, under construction have not been made so far, this study attempts to identify the characteristics by conducting load tests using experimental girders. Baslcr's formula for calculating ultimate shear strength was applied to U-shaped steel girders with diagonal web members to validate the formula by comparing it with the experimental results. In addition, reproducibility of the experiments was analyzed using a program for analyzing elasto-plastic finite displacement. Thus, the programs for the analysis and the conditions used as a basis for numerical studies of the ultimate shear strength of girders are verified.
