Abstract

The long-term project for seismic instrumentation of a 16-storey reinforced concrete cast-in-place dwelling building (str. Roz 15, Chisinau, Republic of Moldova) has provided data on structural response during moderate-magnitude (Gutenberg-Richter MGR = 5·0–6·7) earthquakes since the late 1970s. The effect of soil–structure interaction (SSI) is clearly observed from the recorded response. SSI becomes more pronounced for higher level of ground shaking (larger magnitudes), amplifying and increasing the predominant period of the structure and slightly suppressing high frequencies on the foundation in comparison with the free-field motion. Numerical examples which highlight the problem issues and support the conclusions are presented using finite element method and bidirectional lumped-mass storey-stiffness models.
