Dynamic-geophysical tests of the technical condition and earthquake-resistance of historical buildings

The object of research is historical structures, assessment of their technical condition and seismic resistance. Historical buildings are at great risk of destruction not only due to aging and wear of structures, but also due to the impact of dynamic and static loads of natural and man-made impacts, the intensity of wear can significantly increase and the building can become unsafe. The most dangerous are dynamic loads associated with vibration impact on structures from the passage of heavy vehicles and impacts from earthquakes. To assess the technical condition of historical buildings required a reliable non-destructive method of natural oscillations for assessing the degree of their wear and seismic resistance. That is, the method of researching historical structures should be non-destructive. It is proposed to use new non-destructive dynamic-geophysical method based on background microseismic vibrations of soil construction system for the integral assessment the technical condition and earthquake-resistance of historical buildings. The result of non-destructive studies by the method of dynamic-geophysical testing of historical structures will be an assessment of their technical condition and seismic resistance.
