Experimental Analysis of Composite Timber-Concrete Beam with CFRP Reinforcement

The paper deals with current issues in research of
advanced methods to increase reliability of traditional timber
structural elements. It analyses the issue of strengthening of bent
timber beams, such as ceiling beams in old (historical) buildings with
additional concrete slab in combination with externally bonded fibre -
reinforced polymer. The paper describes experimental testing of
composite timber-concrete beam with FRP reinforcement and
compares results with FEM analysis.
