"This paper summarizes pieces of knowledge, which authors obtained from solution of problems with utilization of experimentally obtained modal characteristics (frequencies, natural modes and damping) for analysis of structural state of structures and simple structural elements, especially for damage localization of structures. The state deterioration of beams was done by static and dynamic fatigue loading. After each step of loading a complete modal analysis was performed to determine modal parameters of the beams. In particular, modal assurance coefficients MAC, coordinate modal assurance criterions COMAC, changes of a mode surface curvature CAMOSUC, changes of a modal flexibility matrix and curvatures of changes of a modal flexibility matrix defined by authors were computed. Pieces of knowledge obtained on simple structural elements were used for an analysis of a development of the state of three road pre-stressed concrete bridges in Czech Republic"@en . . "Praha" .
