Abstract

Wooden beams have been traditionally used for centuries as the supporting elements for roofs. Long exposure to 
environmental conditions and aging cause deterioration and decay of the wooden beams in historical structures, whereby restoration or strengthening is often needed to preserve its historical and archaeological value. This research addresses wooden beams strengthened using Fiber-Reinforceded Polymers (FRP). Numerical modelling is carried out by Finite Element Method (FEM) using a commercial Simulia ABAQUS software ABAQUS, taking into account the anisotropic nature of wood materials and nonlinear behaviour. Validation of the numerical modelling procedure was made by conducting FEM analysis of previously tested two wooden beams: solid wooden beam and FRP-strengthened wooden beam. Description of the modelling procedures for the two beams are described. Agreement between the numerically obtained and the experimentally observed flexural behaviour and failure validates the numerical modelling and analysis approach for investigating and design of various configurations for strengthening wooden elements. A numerical study was conducted to investigate several fiber composites strengthening schemes for wood beam.
