Dynamic characteristics as indicator of structural integrity

Detecting structural state of historical monuments and their adequate strengthening is very complex problem and requires cooperation among various specialists. Real state of complex structures, as are historical monuments, can only be established experimentally. It is preferable that these experiments cause no harm to the structure and still give required information. Dynamic tests are the one that fulfill these requirements. In this paper outlined are usage examples of various dynamic tests (ambient vibrations, impulse excitation and transfer function tests) in order to determine dynamic characteristics and to conclude about the structural behavior and state. This knowledge was then used to define a mathematical model, choose the best strengthening method and to simulate structural response to extreme loading conditions.
