| Sumario: | On November 15, 2004, the city of Cali was affected by the Pizarro earthquake. Several buildings were damaged and about 20 of these suffered considerable damage. Before the earthquake, some of the buildings had been seismically retrofitted, which raises questions regarding the effectiveness of the retrofit with respect to the dynamic parameters of a building. This paper describes a series of ambient vibration tests that were conducted on a building in Cali after the Pizarro earthquake both prior to and after seismic retrofit. Changes in the dynamic parameters of the building due to the retrofit were analyzed using digital processing of the acceleration measurements. Specifically, an increase of the natural frequencies of the buildings in the range of 30% to 50% was observed after seismic retrofit. |
