The Closure Scheme Optimization Analysis of Multiple Large-Span Prestressed Continuous Beam Bridges

Abstract:

It is critical to choose a reasonable closure scheme for the construction or post- construction state of multiple large-span prestressed continuous beam bridges. The feasible closure schemes were analyzed and evaluated. The optimum closure scheme analysis method was proposed. Take Wei river bridge for instance, by deformation, internal force and stress comparison, and construction roubustness analysis, the optimum closure scheme is set down to ensure the girder close smoothly with reasonable internal force.
