FIELD: construction.
SUBSTANCE: method includes selection of measurement points, installation of vibration sensors in the selected points, recording of vibrations and assessment of object vibration frequencies and amplitudes. Measurement points are selected depending on volumetric configuration of the object. Vibrations are recorded by X, Y, Z coordinates of permanent natural or man-induced micro-dynamic background of the object. Frequencies and amplitudes of natural object vibration are preliminary calculated to analyze changes of dynamic object characteristics by means of math modeling. Frequencies and amplitudes are calculated in minimum loaded status, which is characteristic for its maximum load carrying ability. Number of overtones is determined while dynamic characteristics are calculated. Measurable values of overtones are subject to changes to a maximum extent when load is increased to the object. Vibration sensor position is selected under condition of the maximum shift due to natural object vibrations tones used for analysis. For this purpose the parameters are assessed on real object. By comparing measurement results with the values of similar parameters resulted from math modeling, an assumption can be made on the rate of load bearing ability approximation to its maximum values.
EFFECT: real values of construction structures or their parts or elements status, changes in time during operation by means of automatic monitoring of construction structures.
