Paper Abstract

Prestress loss is critical to impact the safety of prestressed reinforced concrete (RC) structures. Unfortunately, up to now, there are no qualified techniques to handle this issue. This paper proposes a life-cycle concept to monitor the full-scale prestress loss of RC beams utilizing optical fiber distributed sensors. And the optical fiber distributed sensors-based smart steel strands and load cell were configured. A prestressed RC beam with embedded smart steel strands was built to illustrate the above methodology. The prestress loss data obtained from the smart steel strand and load cell agrees well, and also matches that from the theoretical code.
