| Abstract: |
To study an economic feasibility with respect to the application of high-performance steel and high strength wire for long span cable bridges, structural analyses and trial designs were performed. In order to compare trial design with previous real design, the practical cable bridges, which type are suspension and cable stayed, were selected. Based upon design method and appropriate assumption, decrease of wire/steel weight and construction cost are evaluated. The results showed that the steel weight and construction cost could be reduced certainly by using high performance steel and high strength wire, although the design stresses of some plates in box girder are not governed by material strength due to the stability of stiffened plates and the limitation of minimum plate thickness or specification for bridges. |
