摘要：

Applying Operational Modal Analysis (OMA) one can extract modal properties of structure (eigenfrequencies, eigenforms and modal damping) on the basis of vibration measurement only - without excitation measurement, what is very complicated in case of big structures. This great advantage of OMA makes this method more common for civil engineering application. The two main techniques are used in OMA, one uses data processing in time domain, the second in frequency domain. The paper presents the comparison of these two method in application OMA for engineering structures. (C) 2014 The Authors. Published by Elsevier Ltd.
