The paper deals with analysing the level of building safety on basis of non-destructive tests results. The non-destructive tests proposed consist of determination of physical and mechanical characteristics of concrete specimens. The devices used for these determinations as Pundit Lab and Hammer Digi-Schmidt are in according with European and Romanian norms. The results obtained from tests according to European Norms for testing hardened concrete proved that the use of non-destructive testing provides plausible values on compressive strength of concrete specimens. The values are used for modelling Reinforce Concrete structures in order to develop a comparative study of buildings response under seismic actions. In the second part of the paper the influence of irregularities on dynamic amplification phenomenon is emphasized. The results are conclusive and are discussed both on the charts and analytical results obtained with help of structural analysis program Autodesk Robot.
