During the construction of thin plated block joints, axial and angular misalignments occur, which lead to additional stresses at this special structural detail. This results potentially in a not proven fatigue strength. Within the thesis, a concept for the assessment of geometric imperfections, which may occur at the block joint, is developed. For typical thin-plated specimen, imperfections are recorded and statistically analyzed. Component tests with typical boundary conditions for full scale structures are carried out to determine the fatigue strength behaviour of the butt joint. With the results of measurements and tests, tolerances with regard to fatigue strength are derived and a recommendation for the measurement and evaluation of imperfections of thin-plated block joints is developed.
