abstract Wooden structures with bolded joints and cut-outs can be reinforced with textile composites, which offer a load adapted fibre orientation. Because of the anisotropic material behaviour of the wood and the textile reinforcement complex stress and strain effects occur at bolded joints and cut-outs. Extensive experimental research using modern, optical 3D measurement methods is conducted for the determination of the complex strain fields at bolded joints and cut-outs of reinforced wooden structures. In addition, the finite element method is utilised for selected parameter combinations as a support. Key words: textile reinforced wooden strucutres, bolded joints, experimental strain analysis
