| Abstract: | To solve current stiffness problems of long-span cable-stayed bridges,a new cable-stayed bridge with carbon fiber reinforced polymer(CFRP)and steel composite stay cables was proposed.Firstly,the de-sign strategies and procedures for the proposed cable-stayed bridges were introduced.The equations to calcu-late the material amounts and costs of the proposed cable-stayed bridges were also derived.By doing this,the economic behaviors of the composite bridges,which were the emphasis of this paper,were then studi... |
