DESIGN OF CONCRETE FLEXURAL MEMBERS STRENGTHENED IN SHEAR WITH FRP

摘要

The present study describes a simple design model for the calculation of the calculation of the fiber-reinforced polymer (FRP) contribution to the shear capacity of strengthened RC elements according to the design formats of the Eurocode, American Concrete Institute, and Japan Concrete Institute. The key element in the model is the calculation of an effective FRP strain, which is calculated when the element reaches its shear capacity due to concrete diagonal tension.
