Abstract

Abstract

The flexural behaviors of pre-stressed C/BFRP-concrete composite beams were experimentally studied, wherein C/BFRP is carbon basalt fibers reinforced polymer.The effects of hybrid modes and prestress levels on the bending behaviors of the composite beams were investigated.The load carrying capacity, stiffness, deflection and ductility of the beams were also discussed.The experimental results show that prestressed C/BFRP can effectively improve the bending behaviors of the composite beams, delay the initiation of the cracks and improve the ductility of the beams.The composite beams also have higher secondary stiffness after the yielding of steel reinforcing bars.
