| Abstract: |
This paper presents the prototype design results of a suspension bridge of which main span reaches up to 2800m. A new design code (draft) developed with supports of the Super Long Span Bridge R&D Center in Korea has been applied to the design. Influences on the design of the main cable, the steel pylon and the orthotropic deck plate are presented. Moreover, the result of optimization on the deck cross-section by wind-tunnel test is summarized. In addition, a preliminary study on a bridge design life has been performed. Important infrastructures such as super long-span bridges may need a longer bridge design life than that of other structure. A bridge with a longer design life essentially requires higher construction cost. A proposal to raise economical efficiency is suggested. |
