Resumen:

The main results of the response of a building instrumented with accelerometers during 31 seismic events, between 1990 and 2018 are presented. The building is a 17-storey reinforced concrete structure located in a soft soil of Mexico City. The main purpose of this work is to present the variations of the most significant vibration frequencies of the building. The analyses of the seismic records are studied with a simplified model and by using a system identification technique based on the modal minimization and N4SID subspace methods. © 2019 9th International Conference on Structural Health Monitoring of Intelligent Infrastructure: Transferring Research into Practice, SHMII 2019 - Conference Proceedings.
