An Analysis of Dynamic Behavior of Damaged Reinforced Concrete Slabs

Popis výsledku v původním jazyce

The paper describes the analysis of dynamic behavior changes of four reinforced concrete slabs in dependence on their damages. The reinforced concrete slabs were tested in four-point bending to get a constant bending moment in the mid-section of the slabs. The state deterioration of the slabs was done by static and dynamic fatigue loads in several steps. After each load step, a complete experimental modal analysis was carried out. Modal characteristics estimated after each load step were mutually compared using five different methods. The identification of the damage of the slabs was done based on a position and a size of the determined values from each method. The results were compared with the measured positions of the real damages.
