RESEARCH OF RELIABILITY AND LONGEVITY OF FERRO-CONCRETE CONSTRUCTIONS

In this article the results of extensive experimental author's works r were generalized, the questions of processes of concrete balancing of various classes in various consolidation conditions, and also economy of the energy spent for consolidation of concrete by using solar energy are considered. The analytical expressions of the constructed histograms )(*xF and )(*xf are developed, and laws of distribution of functions are created. Considering casual parameters, conditions of limit states for construction were developed. The defining parameters of these conditions can be used in the solution of statistical questions of hardness, deformation or existence of cracks in ferroconcrete constructions. The solution of a question is considered, the calculation on durability and stability against cracks of the lower belt of a ferroconcrete farm is made. The costs of parameters of probability and reliability are established and the corresponding analyses are carried out.
