Optimization of Closure Jacking Forces in Multispan Concrete Rigid-Frame Bridges

AbstractCreep, 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 segment before casting to improve the stress state in the piers. Multis...
