A study conducted over a longer period of time for an architectural heritage building from masonry is presented. The specific features of the asymmetric structural systems, the normative provisions in Romania, the strengthening works possibilities necessary after the action of severe Vrancea earthquakes for these systems and also of structural analysis using instrumental data processing techniques are considered. The results obtained in three stages- before, during and after the strengthening works, from Fourier spectra as vibration periods, are compared. Influence of dynamic amplification effects (the amplification of seismic acceleration of the ground on the height of the building), the establishing seismic risk class of the building or of the type of soil foundation are some aspects taken into consideration. Given that post-earthquake instrumental data are not conclusive if there is no pre-earthquake data (as initial data), the study presented is an important step in the analysis of seismic risk and in prevention and protection at disaster. The role and importance of structures monitoring are emphasized in the Romanian seismic design code, some national standards and regulations (with established vibration limits), in the tracking behavior in time of constructions code etc.
