Abstract: 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.
Abstract: 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 fiber - reinforced polymer. The study evaluates deflection of a selected group of timber beams with concrete slab and additional CFRP reinforcement using different calculating methods and observes differences in results from different calculating methods. An elastic (EN 1995) calculation method and evaluation with FEM analysis software were used.
