Gordo, J.M. e Guedes Soares, C. (2004), “Experimental Evaluation of the Ultimate Bending Moment of a Box Girder”, Marine Systems and Ocean Technology, Vol. 1, Nº 1, pp. 33-46.

The results of a four points bending test on a box girder are presented. The experiment includes initial cycles of loading allowing residual stresses relief and two indirect methods are presented for the evaluation of the residual stresses levels. The moment curvature relationship is established for a large range of curvature, the ultimate bending moment and the post buckling behavior is characterized. The distribution of stresses along the loading process is presented and the increasing lack of effectiveness of the stiffened panels is identified including an important inefficiency on the panel under tension load.
