Abstract

In this paper some results of an experimental investigation on real-scale RC (Reinforced Con- crete) and PRC (Pre-stressed Reinforced Concrete) beams strengthened in flexure with FRP laminates devel- oped at Material Testing Laboratory of the Department of Constructions and Transportation Engineering of the University of Padova are shown. Externally bonded FRP reinforcement is applied with different modali- ties, using different types of end-anchorage devices and, in some beams, with pre-stress transfer. After the characterisation of the single materials, four points bending tests are executed and failure and cracking modes are studied with particular attention to the behaviour of the anchorages made both with resins and different types of mechanical devices.
