Dynamic Response Monitoring of a High-Rise Building Floor system in Mexico City under Human Activities and Vehicular Induced Vibrations

This paper presents the dynamic behavior under vibrations of a high-rise building floor system located in Mexico City. The building stands on highly compressible soils and is exposed daily to intense vehicular traffic. Its structural configuration consists of large open-plan office spaces, with reinforced concrete slabs supported by a steel truss system. Controlled forced vibration tests were conducted to quantify the vibrations generated by walking, jumping, and running. Also, a network of seismometers was deployed to continuously record vibrations induced by human activities and vehicular traffic over a one-week monitoring period at various building levels. The collected data were analyzed and the results were compared against standards and guidelines for evaluating human comfort and structural safety under vibratory excitation. The results of this study demonstrate that considering human activities and vehicular traffic in the vibration performance in buildings of large span floor systems located is important in the func-tionality evaluation of buildings in urban areas.
