- Abstract
- The problem of an estimation of residual carrying ability and reliability of bent ferro-concrete designs is considered. À maximum load determined on limiting value of durability and deformability of concrete in a design is choose the measure of carrying ability. Reliability of a design is characterized by an interval of the top and bottom values of probabilities of functioning of a design on durability of concrete. The material of the minimal tests on volume and new methods of calculations on the basis of the theory of opportunities are used for calculations. In practice (15-20) % of ferro-concrete designs fail on decrease of durability of concrete. Residual carrying ability and reliability of ferro-concrete designs are estimated that allows to warn failures.
