Behavior of CFRP-Prestressed Concrete Beams under Sustained Load at Low Temperature

Abstract

The behavior of precast concrete beams prestressed using carbon fiber-reinforced polymer (CFRP) rods was studied under the combined effects of sustained load and low temperature. Three 13-year-old concrete T-beams were tested, including two with CFRP rods stressed to different levels and one with steel prestressing strands. Test beams were exposed to
