STIFFENING GIRDER ERECTION METHOD OF GROUND-ANCHORED SUSPENSION BRIDGE
A stiffening girder erection method of a ground-anchored suspension bridge is provided. Clips for all hanger rods of a space main cable suspension bridge are installed such that design center lines of the clips are located in a vertical plane. A first stiffening girder section is installed at a position away from a first tower at a preset distance in a longitudinal direction. A second stiffening girder section is installed at a position away from a second tower at the preset distance along the longitudinal direction. A plurality of third stiffening girder sections are installed one by one in a direction respectively from the first stiffening girder and the second stiffening girder toward a mid-span until a mid-span closure is completed. An azimuth angle of a main cable around a central axis thereof at each of the clips is measured.
