Long-Term Characteristics of Prestressing Force in Post-Tensioned Structures Measured Using Smart Strands

open access: yesApplied Sciences, 2020
The proper distribution of prestressing force (PF) is the basis for the design of prestressed concrete (PSC) structures. However, the PF distribution obtained by predictive equations of prestress losses has not been sufficiently validated by comparison ...

Analysis of Short-Term Prestress Losses in Post-tensioned Structures Using Smart Strands

open access: yesInternational Journal of Concrete Structures and Materials, 2022
The proper estimation of prestressing force (PF) distribution is critical to ensure the safety and serviceability of prestressed concrete (PSC) structures. Although the PF distribution can be theoretically calculated based on certain predictive equations,
