LONG-TERM DEFLECTION CONTROL IN CANTILEVER PRESTRESSED CONCRETE BRIDGES. II: EXPERIMENTAL VERIFICATION

To continue a preceding study on the long-term deflection control of prestressed concrete bridges, this paper presents findings from the experimental study. The objectives of the experimental program were to confirm the accuracy of the constitutive modeling described in the first paper for time-dependent analysis of prestressed concrete bridges and to verify the concept of the new deflection control method. Experimental findings show that the constitutive model and numerical analysis can be used to forecast the long-term behavior of prestressed concrete structures, and the realistic feasibility of the deflection control method is verified. A numerical simulation is conducted on the prediction of a segmentally constructed cantilever prestressed concrete bridge. Numerical simulation indicates that the new deflection control method is practically feasible to control the long-term deflection of the bridge and to increase the span of a prestressed concrete bridge.
