abstract The article presents the analysis of failure for a reinforced concrete beam with a low level of reinforcement, made of high strength concrete, in the process of static deformation in comparison to experimental results. On the basis of its ultimate uniaxial compressive strength, the methodology for defining the parameters of the constitutive model for high strength concrete was developed. The comparison of the obtained results indicates the correctness of the assumptions and constitutive models of the high strength concrete and reinforcement steel, and also the effectiveness of Crisfield’s arc length method and the Newton- Raphson iterative solution with adaptive descent. The numerical results of the smeared crack patterns proved to be qualitatively agreeable, regarding the localisation, direction and concentration, with the experimental results.
