Sažetak
Measuring forces in tensioning bolts was done by measuring the deformation of tensioning bolts using strain gauges. Control measurements were performed in two ways, by measuring the displacement of tensioning bolts and by method of measurement natural frequencies of tensioning rods (strings). Results obtained by measuring with strain gauges were confirmed by method of measuring natural frequency of tensioning bolts. This method is approximate and can be used as a control. For accurate measurements it is necessary to apply methods that can accurately determine the natural frequencies such as the method of excitation and response by measuring the phase angle between them. The distribution of forces in upper tensioning bolts deviates less than 4% from mean value force, and the same situation is in the lower section bolts.
