Abstract

Abstract

Analysis of prestress loss of concrete structure strengthened with prestressed CFRP plates in tension and using stage is one of the key problems of prestressed CFRP plate technology.Based on the analysis and summary for the existing reinforcement technology of prestressed CFRP plates, using our current Code for Design of Concrete Structure for reference, separately calculate the prestress loss of CFRP plates used to strengthen concrete structures, and present the calculation method of every prestress loss.The estimated value for prestress loss of concrete structure strengthened with prestressed CFRP plates is suggested to be 10% ～ 15% tension control stress based on test．
- strengthen,
- carbon fiber reinforced polymer plates (CFRP plates),
- prestress loss
