Experimental modal analysis (EMA) is the study of a structure’s dynamic properties (natural frequencies, damping coefficients, mode shapes, etc.) using experimental data. FAI isable to provide a one-stop-resource for structural engineering issues including analyzing a problem, engineering a solution, verification, as well as oversight of fabrication and installation, as required.
