Shrinkage and Creep Analysis of a Continuous Rigid-Frame Bridge with Density Gradient Concrete
In consideration of the excessive mid-span deflection and box girder cracks of continuous rigid-frame bridges, this paper analyzes the maximum first principal stress and mid-span deflection increment of a continuous rigid-frame bridge with density gradient concrete under shrinkage and creep effect. The maximum first principal stress increment at main span is 0.084MPa and mid-span deflection increment is 73mm after 10 years for continuous rigid-frame bridge with density gradient concrete, which are smaller than a continuous rigid-frame bridge with normal concrete. All of that show that continuous rigid-frame bridge with density gradient concrete reduces effect of shrinkage and creep. The research provides a theoretical basis for the successful application of continuous rigid-frame bridge with density gradient concrete.
