Annotation: In this article questions of optimum level reliability of building structures are considered from economic-probabilistic positions and aprioristic risks theory. The model is formulated on the basis of long- term experiences of reliability estimation of steel structures in the various probabilistic technic. In the model are used general laws for structures failure, property of failure curve, structures reliability which is designed on codes. The material is stated regardless to design schemes of structures and stochastic loads. In practical calculations it is offered to operate with simple mathematical models with dimensionless parameters. The social and economic importance of building structures is considered by all known and well proved Parameter of the Economic Damage. Application of offered model is illustrated on an example of probabilistic optimisation of steel community tower. The formulated approaches can be taken as a principle rationing of responsibility factor of buildings structures and also are used for definition of risks at insurance estimation of building structures.
Keywords: reliability optimum level, failure probability, failure risk, parameter of an economic damage, economic-probabilistic methods, stochastic loads, probabilistic optimisation, social and economic importance.
