Abstract

Abstract

It is presented a primary study of strengthening reinforced concrete beam using prestressing CFRP sheets and its processing technology of strengthening in laboratory.It was studied that the cohering properties of CFRP sheets and concrete,the measured effective prestress which could be applied to the reinforced concrete beam.By studying and adopting a new anchoring measure,prestress can be effectively transferred to the reinforced concrete beam,and the effective prestress applied to the reinforced concrete beam is 70%～80%of the total prestress.The experimental results are valuable for applying in engineerings.
- CFRP sheets,
- strengthening,
- anchoring measure,
- effective prestress
