This paper provides information about changes of resonant vibration frequencies for concrete and reinforced concrete (RC) beams. The objects of research were concrete beams of different dimensions and RC beams. The concrete beams were damaged by stage of cutting but RC beams were damaged by stage of static loading. After each stage of damage, the resonant vibration frequencies were determined. The parameters change their values while cutting or loading the beams due to cracking. On the basis of the obtained results from different beams, an effort was made to correlate the different dimension of beams, influence of reinforce and the damage of the tested beams with the changes of the modal parameters.
