Study of non-metallic reinforcement influence on the characteristics of cement concrete beam samples properties

The article presents the results of a study strength characteristics beams reinforced with non-matel rods. Tests were performed on concrete samples composite and metal reinforcement different diameters. Based study, tensile in bending modulus elasticity determined. Graphs dependence beam deflections load are constructed based testing polymer reinforcement. A comparative analysis work was carried out using example rod diameter 8 mm, which indicated higher In turn, steel reinforcement, respectively, mm 10 has adjacent values. This allows practice to use smaller cross section.
 corresponding modeled Lira-SAPR software package. simulation showed that reduced deflection rods at 30 kN, 40 kN an average deviation -22%. At same time, convergence experimental values discrepancy within 10%. Thus, modeling operation systems requires clarification, or introduction additional coefficients calculations.
