Vibration Instrumentation in Analyzing the Dynamic Structural Behaviour

Article Preview

Abstract:

Ambient vibration instrumentation is a non-destructive in-situ testing method that can be used to assess the dynamic properties of a building. By analyzing the time histories of accelerations, velocities and displacements (both instantaneous maximum values, or averaged RMS values) and applying specific evaluation criteria, we can estimate the extent of any potential damage. In 2016 and 2021, the ISIM Timisoara building underwent in-situ testing through ambient vibration measurement, using different sensor placement schemes (horizontal, vertical with an external sensor, and sensor at the last level), to accurately characterize the complex structural system. Furthermore, an analysis of the interaction between the structure and the soil is also provided. The approach outlined in the article assists in evaluating the national-level vulnerability of the built environment.
