Title of the articleBy evaluating the strength, hardness and fracture toughness of bent reinforced-concrete elements, strengthened concrete of steel fiber «jacket» on the basis of computer modeling in PC «ANSYS»
Abstract.Problem statement. The purpose of the work poses particular strength, hardness and fracture toughness of bent reinforced-concrete elements, strengthened concrete of steel fiber «jacket» at all stages of loading by varying the most important geometrical, physical, kinematic and power parameters. Results. Conducted multivariate numerical experiment with the use of computer simulation in the PC «ANSYS». A comparison of the results with the experimental data of other authors, which served as a test of the adequacy of the proposed computer model. «Shirt» The optimal values for the percentage of reinforcement steel fiber and thickness. Conclusions. It was found that the most similar to the results of calculations of the experimental data with the introduction of PC «ANSYS» curved concrete deformation diagrams, proposed earlier by the authors [1-2] for bent elements of conventional concrete. FRCC (fiber reinforced cementitious composites) «jacket» increases the bearing capacity of up to 3,9 times to 8,26 times the stiffness.
Keywords.strengthening, fiber reinforced cementitious composites, bendable elements, computer simulation, numerical experiment.
