Abstract: Creep, shrinkage, and temperature drops will shorten the main girder and create additional internal forces in the piers of continuous rigid-frame bridges. Horizontal jacking forces can be applied at the ends of a closure ...

Abstract: Three-dimensional (3D) finite-element analysis of a 106 × 200 × 106-m concrete box girder was conducted to study the effect of solar temperature gradients on long-span bridges during construction. Segments over the internal ...
