Experimental Determination of Modal Damping in Concrete Beams

An approach using experimental modal analysis (EMA) is presented for measuring the material damping properties of concrete beams.  This approach, now popular in mechanical and aerospace engineering, uses hammerblow excitation and frequency-domain analysis to estimate resonance frequencies and modal damping.  Damping properties quantified in this manner are compared to results obtained by traditional methods, which […]...
