Monitoring consists in the deployment of a network composed of sensors in different parts of the target structure and its base. Monitoring allows to assess the safety of the structure immediately following a damaging earthquake to be assessed. On the other hand, buildings are the largest category of structural system, with a high contribution to seismic risk, proving the necessity of developing methodologies to assess the structural health of instrumented buildings. The methodology used in this research uses concepts as pushover analysis and capacity spectrum for a single degree of freedom equivalent system. However, because these concepts involve the fundamental response of the structure, the response is obtained by selecting component signals of specific ranks of the Wavelet Transform, verifying results both in time domain and frequency domain. In addition, the fundamental response is obtained through the use of transfer functions. Considering that the initial information corresponds to acceleration time history records at different levels of a structure, it is necessary to calculate displacements from the time domain fundamental response obtained with the Wavelet Transform. In this way, it is possible to construct the seismic performance curve (Sa-Sd) in real time. Seismic performance curves (Sa-Sd) were calculated for analytic results obtained in a non linear dynamic analysis of the 780-PRE reinforced building. Results show that it is possible to identify the inelastic behavior of the building as well as the fundamental frequency reduction as the PGA of the input in the base increases. In addition, the FICUNI building was evaluated for moderate intensity earthquakes recorded in CISMID-FIC-UNI monitoring network. Results show the building responded elastically for these earthquakes.
