Abstract

The statistical patterns of the distribution of the bearing capacity of compressed short reinforced concrete elements at different levels of symmetrical reinforcement with A500 class reinforcement are analyzed. A numerical modeling methodology is used with an estimate of the distribution parameters of 5,000 pseudo-realizations under the assumption of their normal distribution. The ratio of the element strength values of the required (99.86%) security and calculated according to regulatory conditions is considered. Their discrepancy has been established at high levels of reinforcement, the need to take into account the variability of the ultimate deformations of concrete as a criterion parameter of the design resistance of reinforcement to compression. It is recommended to conduct additional research in this direction.
