Rezumat:

The paper presents an approach able to separate the vibrations
induced by underground traffic from the vibrations induced by other
sources, based on Second Order Blind Identification (SOBI)
algorithm. The signals recorded in different locations of an
instrumented building are mixed signals from different internal and
external vibration sources. The blind source separation algorithm
will estimate the independent vibration sources, as well as the
mixing model of them. This model can be used to determine the
contribution of each source in different measurement points, to
evaluate the effect of vibration sources and their potential for
building damage. The approach has been tested in simulation and on
a building subject to different traffic forms.
