The thesis deals with fasterners influence and sheating board material influence on horizontal bearing capacity of timber - framed walls. Treated timber - framed wall composed of a timber frame and sheating board fixed by mechanical fasteners to the both sides of the timber frame actullay behave like composite structure. Three different groups of test samples with staples distances of s=3,75 cm, s=7,50 cm and s=15,00 cm were experimentally, analiticaly and numericaly (FEM) analysed and compared. Test samples with single fibre-plaster board, double fibre-plaster board and oriented strand board were analysed in the same manner. Obtained analitical and numerical results show good agreement with measured results. The fasteners spacing and various sheating boards have an important influence on craks appering in tensile area of the sheating board, on the ultimate failure force, maximum cantilever bending deflection, slip in the tensile and compressive zone between sheating boards and timber frame as well as on the bending and shear stiffnesses of the prefabricated timber-framed walls.
