From the responses to ambient noise, harmonic excitation and shocks, the dynamic behaviour of usual buildings is identified in the range of 10−5−10−2g. Taking advantage of the demolition, the influence of the light work elements, full precast façade panels, bearing masonry walls and the presence of neighbouring joined buildings is determined. These experiments show that noise measurements efficiently provide reliable data of real interest for understanding the actual building behaviour. Then, the integration of these data in a vulnerability diagnosis is presented. It is shown that regular concrete structures are described by suited beam modelling. Thus for a given structure, taking into account the noise data, the adequate beam model and maximum tensile and compression strains of concrete and steel as damage criteria, two levels of ground acceleration can be determined, namely the Seismic Thresholds of Elasticity (STE) and of Yielding (STY). Quantify the levels that onset the structural damages and the plastic hinge may be a useful tool for vulnerability diagnosis. This concept presents the practical advantages to be based on real data, to minimize the
