On the Development of Vibration Measurement Methods for Building Structures

Vibrational processes contain useful information about the properties of both the signal source and the medium through which they propagate. Control of vibration parameters of structures is an integral part of monitoring. There are various methods and means for measuring vibration processes in building structures, as well as for recording them. Advances in technology and electronics make it possible to continually improve the parameters of vibration devices, reduce their size, and create fundamentally new sensors. Examples of vibration measuring equipment used by employees of the Institute of Continuous Media Mechanics for testing large-scale building structures over the past 25 years are given. The results of vibration measurements of large-scale structures are shown, as well as the evolution of the natural frequency of the building structure during its long-term monitoring.
