DETERMINATION OF THE LEVEL OF RELIABILITY OF STONE STRUCTURES OF EXISTING BUILDINGS
The article presents the results of calculating the probability of trouble-free operation of the stone wall of one of the existing buildings in Novosibirsk. The calculations were carried out under existing operating conditions, as well as with new, increased values of payloads on interstory oors, which may arise in the case of reconstruction of the building. All the initial data for the calculations were determined based on the materials of the building survey with the involvement, if necessary, of certain reference data. The probability of failure-free operation was determined using existing linearization techniques and moments for the fty-year subsequent life of the building.The results of the calculations showed that, despite the gradual decrease in the probability of trouble-free operation over time, these values have high indicators under existing operating conditions. The reliability of the stone wall is also high in the case of an increase in the payload on the interstory oors with a possible reconstruction of the building. In con rmation of this, the normative value of the probability of trouble-free operation was determined. The comparison showed that the calculated values of the probability of failure-free operation, both under existing conditions and in the case of reconstruction, exceed the normative values.The results obtained can serve as a justi cation for further safe operation of the stone wall. The results also show that in the case of an increase in the values of payloads on the interstory oors, the stone wall has a su cient level of reliability, and work on its reinforcement is not required
