DESIGN AND RESEARCH OF CHANGSHA HONGSHAN BRIDGE – A HARP SHAPED CABLE STAYED BRIDGE WITH NO BACKSTAYS
Hongshan Bridge, which was completed and opened to traffic on Dec.28 in 2004, is a harp-shaped cable-stayed bridge with inclined pylon and without any back-stays. The bridge is 206 m span, which is the longest of this type at present in the world. It is a new concept bridge structure. The mechanical characteristics is that with the elimination of the backstays, the inclined pylon would rely on its own dead weight, serving as a counterbalance to support the dead loads and live loads on the deck. It would enriched the harmonious relationship between bridge construct and natural landscape. In addition, the particularly exquisite shape would be formed, and the conventional design concept would be broken free from the upright pylon in conventional cable-stayed bridges. In this paper, the conceives of design and key technologies are briefly introduced and some studies on the reasonable structural form of inclined pylon of harp-shaped cable-stayed bridge with no backstays are carried out by changing some important parameters from the point of design.
