Abstract:

This paper examines the crushing characteristics of a web girder subjected to a local in-plane crashing load. First, a simplified model of the post-buckling deformation of the web girder is developed. Then this model is used to formulate an upper-bound solution for the plastic behavior of the deforming web girder. Finally small-scale crushing tests of extruded aluminum double-hollow forms are conducted to verify the deformation mode and the upper-bound solution. The web girders of interest for this research are the longitudinal web girders in a unidirectionally stiffened double hull USDH structure.
