The purpose of this work was to develop a substitute material model for the analysis of reinforced concrete structures. This paper presents proposals to solve the problem of limited calculation time, both to perform simulation models and to perform effective numerical or analytical analyses of structural elements in order to achieve results consistent with experimental results. Achieving this aim is conditional upon the determination of the material model parameters, taking into account the type of structure, the system of reinforcement, and the static strength–deformation parameters of the component materials. A universal procedure is proposed for determining the parameters of the substitute material model on the basis of the homogenization function, in which the homogenization coefficient is assumed as being equal to the effective reinforcement ratio of real reinforced concrete structural elements. In addition, the introduction of a new concrete constraint coefficient to this procedure, which corresponds to the proportionality coefficient of biaxial to uniaxial compressive strength, is proposed. On the basis of the conducted comparative analyses, the possibility of using the hypothetical substitute material model for the design of building elements and structures was confirmed. The average values of the obtained results for individual research series did not differ from the experimental results by more than 8.5%, for both the numerical and analytical models.

The paper presents integrated effects of concrete samples size and fibers amount on compressive strength of high-and ultra-high strength concretes based on reactive powders. Ready to use the self -compacting mix of highperformance concrete, was applied. The main aim of the work was to determine compressive strength correlation coefficients for size of cubic samples and integrated compressive strength correlation coefficients for the size of cubic samples including fibers ratio. The article presents the results of experimental tests of compressive strength for 3 sizes of cubic samples, i.e. 40, 100, and 150 mm, with the application of the steel fibers ratio of 0%, 2%, 4% for each sample size. Concrete air content and cone flow test studies were performed for all research series. The obtained results show a diversified influence of the size of the samples and the amount of steel fibers on the results of concrete compressive strength of high-and ultra-high strength concretes based on reactive powders. Namely, the compressive strength correlation coefficient for the size of cubic samples was determined in the range 1.0-1.3, while the integrated compressive strength correlation coefficient the for size of cubic samples including fibers ratio is in the range 1.0-1.47.
