| Abstract: |
In order to examine the feasibility of a 5 km-class super long-span bridge, behavioral characteristics and problems were analyzed in 5K-Bridge technology, and a conceptual design was performed based on the latest and future technologies. As for the material of the main cable, the applicability of the carbon fiber reinforced polymer (CFRP) with low weight and high tensile strength of 3000 MPa was examined and compared with a steel cable with a tensile strength of 2060 MPa. For this review, a two-dimensional parametric study was performed for a three-span suspension bridge with main spans from 2000 m to 5000 m with 500 m span length increments. In addition, a conceptual design was performed for a suspension bridge with a main span of 5000 m to evaluate the tension forces, area of the main cables and structural behavior. |
