AbstractAbout AuthorsReferences
The elastic model of concrete composite behavior is considered. Two–factor “matrix-filler” model of behavior of the concrete composite investigated in the theory of degradation is substantiated. The study of elastic behavior is important in terms of assessing the stress-strain state of reinforced concrete structures. Ten parameters are considered in the adopted model. The study of the concrete composite model was carried out using ANSYS software. Elastic deformations of the model were determined. When simulating the shape and size of the filler, the number and relative position of the filler in the prismatic matrix were changed. The results obtained when simulating were compared with the theoretical model obtained in previous studies. The simulation results confirmed the correctness of the provisions laid down in the theoretical model. The obtained model is proposed to be used when assessing the behavior of the concrete composite in the operated structures.
