Abstract
Purpose: The purpose of the work is to determine the longitudinal bending coefficient for steel reinforced rods of various flexibility.
Methodology: Design and testing of rods with various flexibility with about 10 % reinforcement. Creation of FE models of structures similar to the tested ones.
Research findings: Test results show that coefficients of longitudinal bending in rods are significantly overestimated and do not provide a margin for the structural analysis, which is confirmed by the FE models. The value spread in can reach 38 %.
Value: The dependence of longitudinal bending coefficient is suggested for structures over the entire range of flexibility from 0 l h/ = 6 to 0 l h/ =20 under the dynamic load. The proposed non-linear curve corresponds to theoretical calculations. Systematic studies concern the stability of steel reinforced rods in a wide range of flexibility.
