Abstrait:

Concrete and steel are conventional construction materials for bridges. To achieve longer span and longer life expectancy, bridge engineers are urged to seek the novel material and new technology. Carbon Fibre Reinforced Polymer (CFRP) is a promising composite material attracting increasing attention in civil engineering. CFRP has advantages in high strength, light weight, durability, anti-corrosion performance and low maintenance, which make it suitable for cables in super long cable supported bridges. This paper intends to compare the Life-Cycle Cost (LCC) of a super long-span cable-stayed bridge using CFRP cables with the same bridge using conventional steel cables. The result indicates that, although the super long CFRP cable-stayed bridge shows a higher initial cost, its overall cost from the whole life-cycle perspective is more favourable comparing to the conventional steel ones.
