Fibre reinforced polymeric (FRP) composites have been successfully utilized for strengthening elements made of traditional materials, such as wood. A research program carried out at The Faculty of Civil Engineering and Building Services of Iaşi tested the structural response of wood beams strengthening using carbon fibre reinforced polymeric composites, in different solutions.

The need for realistic analysis of structural behaviour of strengthened timber beams pushed researchers to find analytical and numerical evaluation methods that can correctly replace experimental programs, thus lowering the costs imposed by laboratory tests. The paper presents analytical computations and numerical modelling studies, involving three strengthening methods of timber beams using FRP composites.
