Abstrait:

This paper mainly studies the mechanical properties of steel-concrete composite beams reinforced with trapezoidal prestressed un-bonded retrofit (TPUR) system. The prestressing of CFRP plate through the jacking of columns can not only apply the prestressing force to the main beam, but also provide upward lifting force to the bottom of the main beam to reduce the deflection of the original structure. Moreover, the surface treatment of steel beams is not required in the TPUR system, which can improve the speed and efficiency of reinforcement construction. The effects of the amount of CFRP, the prestress level, the height of the pillars and other parameters on the stiffness and bearing capacity of the composite beam are studied through static tests on the scaled model.
