A BRIDGE WITH DOUBLE ECCENTRIC DEPEND ON STAY CABLES

摘要

A bridge double eccentric with stay cables is provided to lower the height of a main girder by building a low main tower at a sub moment point, building a low eccentric member at a main moment point, and installing the stay cables higher than effective height of a main girder section. A bridge double eccentric with stay cables comprises a main girder(20), a plurality of main towers(40), a plurality of eccentric members(50), and stay cables(14). The main towers are built at sub moment points of the main girder. The eccentric members are built at main moment points of the main girder. The stay cables are supported by the main towers and the eccentric members. The main girder receives double eccentric by the stay cables. A PS(Prestressed) steel member(42) is built in the main girder.
