✦ Synopsis

In this paper results are presented from numerical simulations of a travelling patch load on the flange of I-shaped plate girders of three different dimensions. The FEM modelling aims at simulating the load case of bridge launching over multiple supports. The girders have typical bridge girder dimensions, and they were subjected to both patch loading and bending moment. Analyses were made at the load levels of approximately 48% and 67% of the ultimate loadcarrying capacity due to patch loading and a constant applied bending moment. At the higher load level damage in the form of accumulating plastic deformation appeared in the girder models.
