Abstrait:

Applying carbon fiber-reinforced plastic (CFRP) materials for long span bridge, especially for earth anchored stay-cabled bridge (PEA bridge) has been proposed in this paper. The influence of tower heights on the static responses of the PEA bridge had been investigated. It was shown that PEA bridge with lower tower which has less stiffness resulted in larger horizontal forces on the anchorage. The PEA bridge can avoid challenges of the application of CFRP to the main cable of the suspension bridge, such as, bending, shear and lateral compression at suspender connections and tower saddles. Compared with the other suspension bridge, the PEA bridge shows slightly higher vertical stiffness. The limit span of the PEA bridge was inferred the same as the suspension bridge.
