Tests on ultimate strength of hull box girders made of high tensile steel

Gordo, J.M. / Soares, C. Guedes

AbstractThe experimental results of the collapse of three box girders subjected to pure bending moment are presented. The structures are made of high tensile steel of 690MPa of nominal yield stress reinforced with bar stiffeners of the same material. The moment curvature curves are presented covering the pre- and post-collapse regions. The modes of collapse for each box girder are discussed considering the variation on the panel's slenderness. The concept of efficiency of high tensile steel structures is introduced. The concept is very useful to identify the governing parameters affecting the ultimate strength of 3D structures under predominant bending moment.
