Flexural Capacity of Concrete Elements with Unbonded Prestressing

The objective of this research is to provide design guidelines and analysis procedures for bridges with unbonded tendons with particular focus on a combination of unbonded tendons and bonded prestress and/or mild reinforcement. The research will evaluate various ratios of bonded and unbonded prestressing, with consideration of bonded mild reinforcement and PT bars within certain structural members. Guidance on the appropriate resistance factors for these conditions will also be provided.
