Abstract
The objective of this paper is to present the experimental results of the precast prestressed
concrete slabs strengthened by using carbon fiber reinforced plastic (CFRP) plates. The total of 20
specimens was tested by using four-point loading test. The specimen variables included the span
length of the slab, the cross-sectional area and the length of the CFRP plate. The precast prestressed
concrete slab specimens were categorized into five groups according to the modes of failure predicted
by using an analytical model. It was found that the flexural behavior of the strengthened concrete
slabs was in the form of trilinear response which is different from that of the concrete slabs without
strengthening, which was in the form of bilinear response, and the strength and the stiffness of the
strengthened concrete slabs were increased from those of the concrete slabs without strengthening,
depending on the specimen variables.
