GB/T 43144-2023 uses nondestructive acoustic emission detection technology to assess the damage of reinforced concrete beams. It specifies the equipment parameters of the acoustic emission detection system, such as Sensor sensitivity, etc. Detailed preparation for testing, including the layout of measuring points and equipment calibrating. Standardize the inspection process, by capturing and analyzing acoustic emission signals, combined with characteristic parameters to evaluate the degree of internal damage of reinforced concrete beams. The standard provides scientific means for the safety monitoring and evaluation of reinforced concrete beams in construction projects, helping to detect potential problems in time, ensure the safety of building structures, and prolong the service life of buildings.
