Discussion on Curved-Deck Cable-Stayed Bridge with Sightseeing Tower

In this paper, the combined tower structure system of the super long-span curved cable-stayed bridge is composed of the univalent hyperboloid bridge tower, the bowl shaped thin-wall shell podium and the circular sightseeing platform plate. The sightseeing tower and the cable-stayed bridge tower in the scenic spot are two in one. The sightseeing tower improves the vertical stiffness of the super long-span pedestrian landscape curved cable-stayed bridge. The bowl shaped thin-walled shell podium can effectively limit the torsional deformation of the curved cable-stayed bridge deck. Combination 2 ×150m curved cable-stayed bridge, Midas finite element model is established to verify the scientific rationality of the super long-span pedestrian landscape curved cable-stayed bridge with sightseeing tower.
