Prestress Loss of CFL in a Prestressing Process for Strengthening RC Beams [PDF]
International Journal of Polymer Science, 2017 A prestressing system was designed to strengthen reinforced concrete (RC) beams with prestressed carbon fiber laminate (CFL). During different prestressing processes, prestress loss was measured using strain gauges attached on the surface of CFL along the length direction.

Measured temperature effects during the construction of a prestressed precast concrete bridge beam
MATEC Web of Conferences, 2018 Prestress losses in precast concrete beams include the short-term effects of elastic shortening and the long-term effects of concrete shrinkage, concrete creep and steel relaxation. Temperature effects are, however, excluded. The aim of this research was

Pre-Stress Losses in FRP Pre-Stressed Reinforced Concrete – Subject Overview
Archives of Civil Engineering, 2018 Fiber reinforced polymers (FRPs) due to their specific high-strength properties become more and more popular and replace traditional structural materials like conventional steel in prestressed concrete structures. FRP reinforced structures are relatively

Applied 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 ...

Probabilistic Assessment of Prestress Loss in Pretensioned Prestressed Concrete [PDF]
PCI Journal, 1995 The effects of variability in the parameters used to calculate prestress loss are evaluated by a probabilistic prestress loss computer program. The program accounts for the time-dependent effects caused by creep, shrinkage, and steel relaxation. Losses caused by elastic shortening of the prestressed concrete member are also calculated.
