INTRODUCTION

The problem of reliability is a complex problem, the solution of which depends not only on how deeply the engineering methods of the theory of reliability are developed, but also on how much the created theory of reliability is applied in practice, that is, the degree to which reliability is ensured in Construction Practice [1].

RESEARCH MATERIALS AND METHODOLOGY

In order for the construction object to be reliable, it is necessary to carry out complex measures at all stages of construction and operation of its design. The essence of the complex measures that are drawn up to carry out such work depends on the type of this object, the process of its exploitation and other factors.

Measures for the implementation of reliability can be conditionally divided into two groups: measures aimed at increasing the level of continuous operation (increasing the average service life of structures) and measures aimed at increasing the suitability for repair (reducing the

period of repair, its laboriousness, and the estimated cost of repair). Both of them can be carried out in the process of design, construction and operation. Let's consider the factors affecting the reliability of the operation of buildings (Table 1).

RESEARCH RESULTS

Famous, temir concrete constructionalar ikkita group chegaraviy holatlar bravidiy account. This account is currently kungacha amalga oshirilayetganliga and yacht as a result of beraetganliga karamai currently Kun talablariga bera bera oladi deb aith riyin. Because chegaraviy holatlar methodically zhuda lake omilyarni accountga oladigan coefficient, tizim yaratilgan bulsada, irim tasodifiy hollar, kulyad tutilmagan static and airim hollard dynamic yuklamalar can be reduced [2].

One of the characteristic features of the reliability of structural elements is the duration of its operation. The service life of buildings is measured in several decades. But during this period, the physical and mechanical properties of materials will change. Modern calculation methods that take into account reliability make it possible to predict the degree of reliability of a building, taking into account changes in the properties of materials and structures.

To increase reliability, it is necessary to find such volumetric-planned and constructive solutions as early as the design process, so that the possibility of their long-term exploitation is created: the choice of durable materials standard structures; it consists in keeping them from the atmospheric, heat-humidity regime, various technological influences, ensuring its load-bearing capacity when exposed to various unfavorable loads.

It consists in optimizing the structural scheme of the premises in increasing the degree of reliability, approximation of the elements to be assembled, and reducing the number of interconnected nodes. In turn, increasing the reliability of nodes and details of structures, the use of standard elements in design, serve as an important factor in increasing the durability of buildings for the long term. In the overhaul or reconstruction of buildings, materials that meet the standard requirement, are unified, tested many times, the technology of their production is also well established, the quality of such materials is much higher than that of other similar materials. That is why the standard products of the construction industry meet the economic and reliability requirements of the building under repair. Buildings are exploited in certain climatic, temperature-humidity and production conditions.
