Annotation: A model of the operational process based on using a probability of a no-failure operation is given in the article. A probability of a no-failure operation is used for estimating a technical state of separate elements, structures and a building as whole, as well as for forecasting a wear. When determining a probability of a no-failure operation of separate elements, the Monte Carlo method is used. A feature of the technique suggested is the use of a mixed distribution of stresses when determining a reserve of durability obtained by processing the data of the deterministic design of elements by the method of marginal states. A probability of a no-failure operation of separate structures and a building as whole is determined by the analysis of structural and technological connection of elements of these systems. Planning the measures of maintaining structures takes into account a variation of values of no-failure parameters when carrying out supervision measures. In the article the algorithm of determining the terms of conducting operational measures is offered taking into account a possible level of a no-failure operation. The result of optimizing the schedule of carrying out operational measures is a determination of an assured value of the probability of a no-failure operation of building structures during a given period of time at the set level of financing.
Keywords: building strictures, a no-failure operation, a schedule of operational measures, an admissible level of a no-failure operation.
