Technology of diagnostics and monitoring of state of building structures based on the microseismic vibration analysis

Subjected to microseismic actions, any structure performs vibrations. To thoroughly inspect a building using microseismics, it is desirable to implement a dense system of simultaneous recording of vibrations , but this is rarely possible. We consider another observation system and its potentialities. The vibrations of a building subjected to microseismics are recorded simultaneously at the reference point and the i´th point (groups of points), then location of the ith point (groups of points) is changed and the seismic vibrations are recorded again. These observations allow one to inspect an object using a thin-route system. The problem is to transform records made at different points at different times into the record of standing waves of the entire observation system. We propose an algorithm for obtaining the data of simultaneous recording of a vibration process at different points of a structure for the data recorded at different times using one reference point.
