Abstract

Compared with cable-stayed bridges with pure steel girders, the installation of a steel main girder of the steel⁃concrete composite girder cable⁃stayed bridge is more complicated, and the installation error control is more difficult. In this paper, the composite girder with a double box section was taken as the research object, and a finite element model was established to compare the installation methods of steel main girders. The best installation method was selected according to the principle of safety loading, and the causes of the installation errors of steel main girders were analyzed. The corresponding error control methods were proposed.
