In the present study, ultimate load carrying capacity test has been carried out in order to evaluate the mechanical effects of horizontal stiffeners on the ultimate load carrying capacity. From the experimental results, it was found that, even in case the horizontal stiffeners are eliminated, the ultimate load carrying capacity decrease is much smaller than the decrease of the bending buckling strength of the web panel specified in the general design code. Furthermore, it was concluded that the compression flange of box girders restrains bending buckling of the web panel.
