Estimation of Soil-Structure Interaction Effects in a Building on Soft Soil in Mexico City

https://doi.org/10.58571/CNCA.AMCA.2024.055

Resumen: By using a simplified model, the use of subspace identification methods in monitoring the soil-structure interaction effects is analyzed. For this, a building on a soft soil zone is considered a studied case. The building has been monitored from 1990 to date and has instrumentation that allows tracking the soil-structure frequency and the translation and rocking frequencies due to soil-structure interaction effects. Also, the frequency related to the proper dynamic of the building is estimated. The estimation process is by using a recursive subspace identification method and spectral analysis hrough seismic records. The results show consistency with similar frequency values but minimal variations using subspace estimation methods, with the advantage that it can be automated and incorporated into structural warning systems.
