| 要旨 | This paper discusses the problem of predicting the life of reinforced concrete flexural member. Series of unstrengthened and CFS strengthened beams were tested in the lab to represent the highway flexural members. The beams were monitored closely during their degradation process by measuring their change in mid-span deflection, strain in steel reinforcement and natural frequency. Change in natural frequency is used as the indicator of beam degradation in stiffness. The degradation model is based on experimental observations. The proposed model can predict the life of undamaged specimens as well as specimens that have been strengthened. |
