A 14-storey reinforced concrete building and the underlying soil were instrumented with strong motion accelerographs to study the amplification of seismic waves, the soil-structure interaction and the structural response to earthquakes of buildings founded on soft soil, such as the lake-bed area of Mexico City. A detailed investigation of the geotechnical properties of the site and of the structural characteristics of the building was performed, including the measurement of the shear wave velocity in the different soil layers. The instrumentation consists of 14 strong motion accelerographs, two of them underground, one in free-field and 11 in the building. In the first three years of operation of the instrumentation, six sets of records were obtained from weak and moderate earthquakes. The main features of the seismic response of the building and its interaction with the soil were derived from the analysis of seismic recordings. Ambient vibration tests were also performed to determine basic dynamic properties. The accuracy of different models of the structure and of its interaction with the soil are discussed. In general terms, the building proved to be rather flexible in both horizontal directions, and the deformations due to soil-structure interaction were not very significant. Vibration periods of the building were found to increase significantly with the intensity of the ground shaking, indicating the non-linear behaviour of the structure, even under small levels of excitation. |
