Abstract
At present, it has been reported that the limit span of a suspension bridge will be around 4000m. In order to realize such super long-span bridge, the development of new construction techniques is necessary. Furthermore, in Japan, the economy and durability by the rational design is strongly demanded. This paper clarifies the elasto-plastic behavior and the ultimate strength of continuous suspension bridge with 4 super long spans. In particular, we examine the effectiveness of applying two boxes and grating cross-section to a main stiffening girder and 2000 MPa high strength cable to the main cable.
