To estimate soil-structure interaction (SSI) effects in two instrumented buildings different models are explored. Both system identification and analytical methods are used to calculate stiffnesses and frequencies associated with SSI effects. The later include procedures from the Mexico City building code as well as commercial software by mean of which piles group effects are also considered. Experimental data from two of the most significant and recent earthquakes recorded in the buildings are analyzed and comparisons suggest interesting conclusions about analytical considerations and actual behavior of the buildings and theirs foundations.
