Safety Analysis of Constructions

Safety analysis method using the theory of tolerance in designing engineering constructions is suggested. For the distribution curves х,у,…, the normal distribution law is accepted. The method allows to reveal some strength reserves and provides equal safety characterized by the factor . Different factors that allow to consider the random character of loads operating on the construction should be taken into account for analysis of constructions. Accuracy of strength analysis and deformability of constructions is resolving for revision of safety factor quantities.
