FIELD: construction.
SUBSTANCE: invention relates to construction in the field of nondestructive testing and is intended for monitoring the technical condition and diagnostics of span structures and supports of bridge structures of various purposes and design in the process of their operation. Method is realized by performing periodic or continuous control (monitoring) of the main elastic characteristics determining the technical condition of the spans and supports: stiffness coefficient of the cross-section of the span structure relative to the bending, stiffness coefficient relative to angular displacements in the support cross-sections of spans, stiffness coefficient of the supports relative to the transverse (vertical) shear, transverse shear stiffness coefficients of a uniform elastic base in the transverse and longitudinal directions.
EFFECT: technical result consists in increasing the reliability of monitoring the technical condition of the bridge structure to ensure its safe operation.
