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 ...

Prestress loss in externally FRP reinforced self prestressing concrete beams [PDF]
Construction and Building Materials, 2015 Abstract Hybrid fiber-reinforced polymer (FRP) reinforced expansive concrete (EC) structural system shows a good potential for delaying concrete cracking and eliminating steel corrosion. In this study, long-term expansion-shrinkage strain development and prestress loss of the proposed system are investigated.

Study on prestress long-term loss of anchor cable considering coupled multiple factors
Rock and Soil Mechanics, 2021 In order to study the long-term loss law of anchorage force and the calculation method of prestress loss of anchorage force, a calculation method of the prestress loss of anchorage force was proposed to account for three factors.
