Figure 2.
The two panel illustration shows longitudinal deformation of a cable stayed bridge from south to north. Panel a presents the full bridge with the south tower left and north tower right, showing the deck profile and cable fans. Bracketed sections labelled A A, C C, D D, E E, F F, and B B mark analysed regions along the span. Deformation magnitude varies along the deck, with notable concentration beneath the central tower region and smaller variations toward both ends. Panel b shows an alternative deformation case with sections labelled C C and I I. The central tower region again shows the largest deck deformation, while the side spans and tower bases show reduced responses.(a) Sagging and (b) hogging moments of the QC towers and girders
