Abstract

Shayong Bridge on Dongguan Binhai Avenue is a special-shaped steel box tie arch bridge with a single span of 120 m and five cable planes. The standard section width of the bridge is 80 m. A new type of spatial special-shaped arch bridge with an ultra-wide deck for urban roads was proposed to meet the landscape and structural stress requirements. The main beam adopted the full-width crossbar beam system, and the arch rib adopted the inverted trapezoidal steel box structure with varying height and width. The rise span ratio of the middle arch rib was 1/3.05, with the design vector height f = 38.00 m. The side arch rib was inclined, the rise span ratio was 1/4.936; the vertical projection design vector height f = 23.5m, and the arch height between the middle arch and the side arch was a golden ratio. In order to reduce the dead weight of the bridge deck, optimize the size of the main beam and arch rib, and solve the fatigue and durability of the orthotropic steel bridge deck, the lightweight composite bridge deck with steel–STC ultra-high toughness concrete was used. This kind of bridge has the advantages of a novel structure, beautiful appearance, reasonable force, low engineering cost, and good structural durability. It provided a new way of thinking for the design of urban ultra-wide landscape bridges.
