Gordo, J.M. e Guedes Soares, C. (2014), “Experimental analysis of the effect of the frame spacing variation on the ultimate bending moment of box girders”, Marine Structures, Vol. 37, pp. 111-134
An experimental study is presented of three box girders made of mild steel subjected to pure bending moment with different spacing between frames. The moment curvature curves are presented, allowing for the analysis of elastic-plastic behavior until collapse and the evaluation of the ultimate bending moment and post collapse behavior for each experiment. The residual stress relief during loading and unloading path is also analyzed. The effect of the span between transverse frames on the ultimate bending moment of the box girder is studied and thus its dependence on the column slenderness of the panel under compression can be established.
