Span Continuous Rigid Frame Shrinkage, Creep, And Construction Control

At present,the continuous rigid frame bridges are in the upsurge of building. In the building of these bridges, there are some problemes such as the stress measured is larger than the value calculated, after the bridges were completed, the creep displacements are far more than the values predicted and there are obvious lengthways displacements on the top of piers for shrinkage-creep. From the view of mechanism, infection factors and computational theories about shrinkage and creep, the article studied these problemes to some extent and took the lead in putting forward the resolvents. These resolvents will play a great role in the creep displacements control of the continuous rigid frame bridges in the future.
