Zyma O. Reliability of main pipeline steel structure

The object is linear part of steel main underground pipeline; the purpose is quantitative assessment of reliability of linear part underground main pipeline steel structure for the influence of aggregate structural, technological and operational factors and the stochastic nature of operating loads and the strength of the structure elements; the method is analytical methods of the theory of deformable solid, mathematical modeling of reliability variation at different stages of the main pipeline life cycle, methods of probability theory; the novelty - improved taking into account the impact of the life cycle stages of main pipeline on the stress-strain state and structural reliability of steel main pipeline; the theory received further development of the determine the reliability of the linear part of the underground main pipeline; at first obtained quantitative estimates of reliability design of linear pipeline at various stages of its life cycle; the results - the method of determining the reliability of the linear part of steel main pipeline structure was developed; at first obtained quantitative estimates of the reliability of the linear parts of main pipelines in different stages of operation of main pipeline; the industry is building
