| Summary: | The aim of the paper is to present some methodological aspects regarding
the determination of the vibration eigenmodes of a spatially
large, symmetric structure and afterwards to show the obtained results
for a spectral analysis of the ground motion in the horizontal plane,
corresponding to steady state micro-tremors. The recorded velocigrams
concern the rigid body motion of the main ring of the structure (translation
along different horizontal directions and rotation with respect to
the vertical symmetry axis) as well as ovalization oscillations (mainly
second order ovalization). The necessary data for the analysis was obtained
through an efficient technique of combining basic records gathered
with the help of data acquisition systems, on site, using three different
schemes for the placement of the recording sensors. |
