In Romania, there are several legislative guidelines regarding the activity of seismic instrumentation/monitoring, which can support this activity in a coherent and effective way (Seismic Design Code, P 100-1/2013, Annex A). The monitoring of the Faculty of Biotechnology building is carried out using 3 Granite triaxial sensors, arranged one each on the top, in the basement and in the free-field. For each of the recordings, the Fourier spectrum, also response and power spectrum, can be represented, using different options related to axes, corrections etc. The processing of the records leads to the determination of the instantaneous maximum values of the accelerations, velocities, displacements. A comparative analysis over time will be presented for the level of vibrations recorded and for the frequency range obtained in free-field, basement, top conditions, as well as an analysis of vibrations from an ambient comfort point of view. Beyond the legislative aspects, this activity responds to the need to know both the characteristics of earthquakes and the structural characteristics of the building.
