Due to the types of construction (steel, concrete etc.), the type of excitation (caused by wind, rail and traffic etc.) in the measurement of engineering structures’ vibration different measurement techniques and different data processing techniques are used. The paper presents the comparison of Classical and Operational Modal Analysis on the basis of engineering structures. The results of vibration's measurements of selected engineering structures with the use of different methods of data processing are presented and discussed in the paper. Dynamic measurements of a structure were performed with the use of a multichannel PULSE system, produced by the Brüel & Kjær.
