Figure 2.
The image shows a three-dimensional underside view of a bridge superstructure. The upper view labels the girder end at the start pier side on the left and the girder end at the end pier side on the right, each enclosed by a red rectangular outline. The lower view focuses on the underside of the girder and deck system. A red dashed boundary separates two structural regions. The left region is labelled continuous section and shows girders supported across multiple piers. The right region is labelled cantilever section and shows a projecting girder segment extending beyond a pier. Columns, cross beams, and deck elements are visible beneath the superstructure, illustrating the structural difference between continuous and cantilever behaviour.Classification diagram of damage occurrence locations
