Laboratory Tests of Reinforced Concrete Beams with the Use of Operational Modal Analysis

Abstract:

This paper presents the potential for the use of operational modal analysis (OMA) in the testing of reinforced concrete elements. The main difficulties encountered by the author when carrying his own experiments in this regard are described. The investigations carried out as part of this research and reported here covered: the identification and selection of a proper test stand, the effect of the loading advancement degree on the eigenfrequencies and damping of reinforced concrete beams. In addition, general tips on the testing of reinforced concrete elements with the use of OMA, which can be useful for conducting other experiments of this type, are included.
