Refined Evaluation of Effective Prestress in the Varina-Enon Bridge
The Varina-Enon Bridge is a cable-stayed, post-tensioned segmental box girder bridge in Richmond, Virginia. A large flexural crack was noted by inspectors in July 2012 which prompted a number of investigations into the current condition of the bridge. Particular focus has been put on prestress …

Testing of the Transverse Tendon Behavior in the Varina-Enon Bridge
Post-tensioned segmental concrete bridges have been used in the United States since the mid 80's. Post-tensioning is very economical and efficient for bridges with very long spans. A segmental concrete bridge uses post-tensioning to connect concrete bridge segments and make a long span bridge. A …

Investigation of the Time-Dependent Longitudinal Flexural Behavior of the Varina-Enon Bridge
… throughout the United States highway system and bridge construction. Over time, the force in the prestressing strands is reduced by delayed strains in the concrete. The accurate estimation of this prestress loss is vital for making good decisions about the remaining capacity of a structure and …
