REMOTE METHOD OF ASSESSING TECHNICAL CONDITION OF BRIDGE STRUCTURE Russian patent published in 2025 - IPC G01M7/08 G01M5/00 

FIELD: measuring.

SUBSTANCE: invention relates to methods of non-destructive testing of bearing capacity of building structures, in particular, to methods of assessing technical condition of span structures of bridge structures when passing excess military loads on them. Remote method for assessing the technical state of a bridge structure is characterized by the fact that the inclination angle of the support section of the span is measured under the effect of a test load located in a position corresponding to the maximum bending moment on the span, using sensors, calculating the deflection from the test load in the middle of the span by the inclination angle of the support section, calculating the predicted deflection from the excess load, the maximum allowable deflection and the maximum allowable stresses in the upper and lower edges of the span from the excess load, deflection in the middle and stresses in the upper and lower edges of the span with their subsequent comparison with the maximum allowable ones, wherein the angular displacement measurement sensors are installed using robotic means, test load used is a robotic load made with possibility of movement and stop by signal from remote control panel, and angular displacement measurement sensors used are inclinometers made with possibility of automatic levelling relative to earth horizon and remote transmission of measurement results to mobile portable computer.

EFFECT: higher safety of personnel in conditions of possible impact of enemy with high-precision weapon on bridge structure.
