Abstract
The study proposes the evaluation of the use of the modal analysis for the survey of parameters of large buildings. To perform this experiment, 71 in situ vibration surveys were performed due to operational actions. The data were processed using FFT and SSI to obtain the spectra in the frequency domain and the verification of their natural frequencies. The experiment was carried out in two masonry towers with a height of more than 44m in order to validate the characterization form through modal analysis.
