Modeling of stress condition of reinforcement concrete structures, with the influence of stress raisers as of periodical profile
To study the properties section of the reinforcing steel in the as delivered and after hardening uniaxial stretching, a comparison of these values with the characteristics of natural samples developed experimental technique using thermo hardened steel reinforcement classes A500S and At800. Consider the diagram expansion of natural samples and samples with remote stress concentrators, in the form of periodic profile. To determine the influence of various factors on rebar in its hardening uniaxial tension, a number of experiments related to the definition: the variability in the properties section of the reinforcing steel, the effect of stress concentrators at the charts of the material in tension zones of reinforcement. To determine the effect of hardening on the uniaxial tensile behavior of the mechanical characteristics of the cross-sectional study of classes of reinforcing bars used samples with different levels of hardening. The analysis of the results of the experiments conducted. To determine the mechanical properties of reinforcement used in non-destructive method based on shock indentation truncated indenter.
