TIME-DEPENDENT EFFECTS IN PRESTRESSED CONCRETE COMPOSITE BRIDGE MEMBERS

This paper shows how to take advantage of reduced creep and shrinkage parameters associated with high performance concrete (HPC) in better predicting prestress losses and deflections at various stages of construction and bridge service. Three examples are presented to illustrate the theory and the significance of accurate analysis compared to standard multipliers.
