INFLUENCE OF THE INTENSITY OF PHYSICAL WEAR AND TEAR ON THE DURABILITY OF MULTI-APARTMENT RESIDENTIAL BUILDINGS

Determining the level of reliability in relation to the operation of multi-apartment residential buildings (MMARB) and determining the intensity function of the accumulation of physical depreciation are important issues regarding the renovation strategy. The distribution of the service life of residential buildings, the function of their reliability and the distribution of depreciation of the buildings under study are interdependent concepts. The deterioration of the object will be the higher, the longer the period of its operation. However, this is not an increase that reflects the life span of the building, nor is it a cost that is directly proportional to its age. The article presents a model and methodology for checking the level of deterioration and reliability of MARB, operated in different regions of the Republic of Uzbekistan, built in the period 1967-2019. The main conclusion was made regarding the mechanism of damage to residential buildings: during the period of operation of the facility, in which the uptime to failure has an exponential distribution, the average remaining uptime does not change at any time. It has been confirmed that after a certain period of non-failure operation, the tested MARBs perform their functions as new buildings.
