Experimental and numerical analysis of concrete slab prestressed with composite reinforcement
Original language description
Behaviour of concrete slabs prestressed with glass fibre reinforced polymer (GFRP) composite bars is investigated in this paper. The main advantage of GFRP bars is their high strength/self-weight ratio. On the other hand Young's modulus is very low compared to steel reinforcement which is the main cause for unacceptable deflections. To eliminate such deflections and to utilize high tensile strength of GFRP bars it is very useful to pretension the bars. During the experimental work a set of three concrete slabs 4.5 m long was casted. Each slab was prestressed with four GFRP bars. The slabs were subjected to four points bending. Each specimen was subjected to ten tow-load cycles and afterwards loaded until failure. Deflection under each loading point andin the middle of the beam span was recorded. Moreover stress at the lower and upper surface was measured. The experimental procedure was modelled numerically in finite element nonlinear software.
