An investigation on the strength and serviceability performance of steel and CFRP plate bonded concrete prisms

Abstract

This paper presents the results of an experimental study on the strength and serviceability performance of plate bonded concrete prisms loaded to failure under three point load tests. The plates used were made of steel or Carbon Fiber Reinforced Plastic (CFRP). The specimens were varied in plate type, thickness, concrete grade and adhesive type. The effects of these variations on the moment capacity, deflection and failure modes were studied. The results showed that plate thickness considerably affected strength and serviceability properties. However, the effect of concrete grade and adhesive type on these properties was less significant.
