Enhancing the Strength and Ductility of Post-Tensioned Segmental Box-Girder Bridges
An investigation was conducted to determine the effect of using external tendons, discretely bonded at intermediate diaphragms, and supplemental, grouted internal tendons on the strength and ductility of post-tensioned segmental box-girder bridges. In the current research program, additional experimental testing, performed on an existing three-span bridge model that was constructed and tested during an earlier study, and an analytical study were performed to examine the influence of improved bonding of external tendons and supplemental internal tendons on the behavior of segmental box-girder bridges. Both the experimental and the analytical portion of the study were carried out in three phases. Results of the tests and computer model indicated that both discrete bonding of external tendons and use of supplemental, grouted internal tendons improved the strength and ductility of segmental box girder construction. Design recommendations for predicting the ultimate external tendon stress and for enhancing the strength and ductility of segmental box girder construction are presented in the report.
