Within the thesis I made a computer program created in the developer mode of Microsoft Excel program. The programming language used is called Visual Basic (VBA). Program can calculate load-carrying capacity of metal dowel-type fasteners such as nails, screws, bolts and dowels in a
different type of single shear, double shear and some multiple shear timber connections. Calculations are based on Johansens’s yield theory which is slightly modified by Eurocode 5. First part of thesis describes Johansen’s equations and their application in Eurocode 5, the second part describes program operation and the equations used for each type of fastener.
