Dense seismic instrumentation and modern devices are a prerequisite to making accurate observations on seismicity and its effects on buildings. In-situ instrumental data contribute to a correct understanding of the importance and of the influence of various factors on the structural dynamic response, as well as their correlation with interest objectives for the building owners/beneficiary. Romanian experience in INCERC after 1977 has demonstrated that damage to buildings was correlated with some changes in the oscillation periods of buildings. This distinction serves to decouple the influences that these Vrancea seismic motions have exercised successively and/or cumulative on the damage state. The rigidity and the values of oscillation periods are influenced not only by visible degradation, but also by a series of deformations and invisible cracks, accumulated in the building structure, which may be significant. In this regard, the determination of the dynamic characteristics of building structures is one of the most important aspects of structural health monitoring.
