"The paper deals with three types of concrete elements and their fatigue damage identification. Three reinforced concrete beams, four reinforced concrete slabs and two prestressed concrete slabs were investigated. They were loaded by static and dynamic fatigue loading during which the location of the damage was monitored and written down. The loading was applied in steps and after each step, the complete modal analysis was done. Modal characteristics were evaluated after each step of loading. Damage identification was done by three different methods based on the evaluated modal characteristics. Results of these methods were compared with written down real damage and suitability of each method was evaluated." . "1" .
