SCHEME OF CONTROL OF ENGINEERING STRUCTURES’ TECHNICAL CONDITION

Abstract

For the English abstract and full text of the article please see the attached PDF-File (English version follows Russian version).ABSTRACT Reliability of artificial structures on the railways is directly related to safety of life of passengers and cargo. The proposed scheme of control of technical condition of the span allows to calculate with a great precision design reliability and to predict its changes, to respond flexibly to the dynamics of the operating conditions, as well as to control optimally the processes by the criterion «reliability-cost». Keywords: railway engineering structures, span, reliability, security, recursive algorithm, optimal interval.
