Dynamic tests and monitoring of the dynamic state of buildings and structures based on microseismic vibrations

Строительная механика

The article considers organizing and conducting dynamic testing of a multi-story residential panel building in Krasnoyarsk. For dynamic testing, a hardware-software complex was developed that implements the standing wave method, allowing to determine the dynamic characteristics of a building by registering microseismic vibrations of building structures. The dynamic test results determined actual natural (resonant) frequencies and their oscillations modes for the building structures. From the analysis of the distribution of the peak values of the amplitudes of natural vibrations, we determined the dangerous zones of the occurrence of destructive processes in the soil of the base of the building, affecting its safe functioning.
