| Descrição: | This paper presents the modal parameters of a 17,5 m high building, due to environmental vibrations, obtained using methods in the frequency and time domain available in the ARTeMIS Modal v.5.0 software, with the aim to evaluate its efficiency to conduct Operational Modal Analysis using data of ambient vibration tests in buildings. In the measurement, the roving sensors technique was used for a total of six test setups, with four TitanSMA triaxial accelerographs. The processing was carried out using the softwares: Geopsy and ARTeMIS Modal, with which no difference was found, and in the analysis five vibration modes were identified through spectral analysis, while the results in the time domain were inconsistent. In addition, the Modal Assurance Criterion (MAC) was used for a cross control between the modal shapes obtained with the two different domains (time and frequency). |
