The purpose of research is development of methods for reliability analysis of structural reinforced concrete elements (on example of reinforced concrete beam) according to criterion of the normal cracks length in tensile zone of concrete. Cracks in tensile zone of concrete in beams leads to displacement of the beam's neutralaxis towards the compressed part of the concrete, thereby increasing the compressionstress in the concrete, to the increasing of the stress in the reinforcement bars on the crack width, to the growth of corrosion processes, etc. This leads to the decreasing of beams mechanical safety and reliability (as a quantitative measure of mechanical safety). The main parameters, which reduce the strength and stiffness of the beam, of the cracksis the length and width of the crack. The article describesthe influence of the cracks length on the reliability of reinforced concrete elements. The article differs from existing approaches in that isitbuilt on a limited statistical dataofcontrolled parameters in mathematical models of limit state. The article alsoconsidersthe influence of cracks in the structuralelement. The methods of reliability analysis allow to assess the mechanical safety of reinforced concrete elements and to make appropriate decisions about the safety, strengthening or replacement of thereinforced concreteelement.

Aerated concrete structures are widely used in construction as load-bearing or filler structures. The article describes the probabilistic approach to estimation of anchor (dowel) pull-out capacity. The article also presents the experimental studies of control samples from aerated concrete and diagrams “stress – strain”. The maximum permissible load values are obtained for the given batch of aerated concrete blocks based on the requirements of ensuring the specified reliability (probability of no-failure). Permissible load on the anchor (dowel) will also depend on the number of anchors in case of set of anchors as a conditional sequential mechanical system in terms of reliability theory. The design equations is given the reliability analysis of anchor (dowel) on pull-out force with limited statistical data and small number of control samples for using probabilistic and statistical approaches.

The article describes a probabilistic approach to the reliability analysis of a flexural reinforced concrete element by the cracking criterion using the provisions of fracture mechanics. Two mathematical models of limit state are proposed for reliability analysis: with the evaluation of the critical stress intensity coefficient directly and through the design concrete compressive strength. On the basis of regression analysis, the relationship between the critical stress intensity coefficient and the design concrete compressive strength is established which can be used in the inspection of reinforced concrete structural elements. The influence of the design concrete compressive strength on the failure (cracking) probability of the flexural reinforced concrete element is analyzed. The numerical example of reliability analysis is given for the reinforced concrete beam by the criterion of cracking. It is noted that the required level of reliability should be set for each structural object individually based on the acceptable risk value using economic and non-economic losses.
