In this paper there are described the results of the experimental testing of the reinforced concrete beam with the different degree of a damage. The damage was induced by the static load. The aim of this work is the investigation of the relationship between the state of structural damage and the dynamic properties of the tested structure. For the excitation of the beam the electrodynamical shaker was used. The shaker was driven by the signal of kind random.
