Abstract
Objective. Research and analysis of parameters of the stress-strain state of reinforced concrete beams using periodic ultrasonic testing in compressed and tensile zones and development of proposals for the application of the method in the inspection and monitoring of reinforced concrete structures in operation.
Method. Experimental studies were carried out using a four-point bending scheme in accordance with GOST 8829-2018 with measurements of deflections in the span center and at the points of load application and concrete deformations on a 500 mm base at the level of compressed and tensile reinforcement with calculation of curvature, recording the appearance and development of cracks and changes in the ultrasonic pulse velocity in the pure bending zone in the compressed and tensile zones of the section and calculating the length of normal cracks.The length of normal cracks was also calculated. Beams made of concrete with classes B25 and B40, with reinforcement coefficients of 0.0149 and 0.0111, were studied.
Result. The relationships between the relative ultrasonic pulse velocity, the change in the relative normal crack length, the section stiffness, the elastic modulus, the relative height of the unbroken concrete section, and the deflections along the beam length at load application points and at midspan were determined. A gradual change in the ultrasonic pulse velocity was determined. In beams with a shear force failure pattern, no increase in the ultrasonic pulse velocity was detected in the tension zone.
Conclusion. The proposed method for analyzing the stress-strain state using discrete measurement of the velocity of an ultrasonic pulse in compressed and stretched zones of reinforced concrete beams can be used in experimental studies and in the inspection and monitoring of operated reinforced concrete structures.
