Abstract

Abstract

Nine continuous concrete beams reinforced with unbonded CFRP tendon were fabricated. Static load tests were carried out for these beams. A new method for CFRP tendon was presented before test to explore the anchorage method of CFRP tendon,whose feasibility was verified through test. Based on test data,it was studied stress of CFRP tendon,distribution of zone of plastic hinge,redistribution of internal force and so on. Then the calculation formula of length of equivalent plastic hinge and that of moment modification were presented respectively.
- unbonded prestressed CFRP tendon,
- continuous beam,
- plastic hinge,
- redistribution of internal force
