Field Study of a Predeflected Steel-Concrete Composite Bridge: Interim Report
To permit verification of design parameters and assumptions governing 'Preflex' beams, field tests were conducted on a skewed simple-span bridge to determine the magnitude of initial and long-term dead load deflections, and the extent of cracking (if any) in the precompressed concrete. Vertical deflections of the beams during construction and under service dead loads were compared with theoretical values. Although the measured dead load deflections were slightly greater than design predictions, the structure's short-term performance was found to be satisfactory. Surveys are to continue for six years so that long-term deflection behavior can be evaluated. (Author)
