CONTROL METHOD OF EXTERNAL COMPOSITE REINFORCEMENT OF BUILDING STRUCTURES

摘要

FIELD: construction.SUBSTANCE: control method of external composite reinforcement of building structures involves thermal loading of controlled surface; irradiation of the controlled surface with coherent laser emission; recording of a field of displacements and detection of defects of composite reinforcement regarding availability of abnormalities of interference bands. Thermal loading is performed by a laser beam with wave length providing maximum energy absorption by a controlled composite coating and a warm-up spot that is less than transverse size of an allowable defect; warm-up energy is dosed by duration of an emission pulse. Point-by-point scanning of the test surface is performed, and the field of displacements is recorded by a method of high-speed electron correlation speckle interferometry.EFFECT: invention allows improving the method's efficiency, reducing the time required for preparatory operations and improving defect detection reliability.3 cl, 1 dwg
