Prediction of Immediate Deflection and Flexural Capacity of Unbonded Posttensioned Concrete Members Strengthened with External FRP Composites

Abstract

Abstract Existing codes and design guidelines do not provide a procedure to compute the immediate deflection of unbonded posttensioned members strengthened with fiber-reinforced polymer (FRP) composites. The existing procedures are only applicable to ... Practical Applications In this study, the two equations of the effective moment of inertia (Ie), recommended in the American code of practice to predict the immediate deflection of bonded unstrengthened reinforced concrete (RC) and prestressed concrete (...
