THE HAZARD RATE FUNCTION OF ELEMENTS STRUCTURES
Journal Title: Збірник наукових праць Українського державного університету залізничного транспорту - Year 2017, Vol 167, Issue 1
Abstract
The article analyzes the theoretical basis assess the hazard rate of elements constructions during the time of life cycle exploitation. The problem became especially actual for Ukraine in the last 20-25 years. Today we must note a rapid growth physically obsolete structures, excessive increase in the number of bridges in need of repair, lack of survey data. In these circumstances, for trouble-free operation and life extension works, we need new scientific approaches to assess and prediction their technical condition lifecycle. Looking realistic efficient algorithms that would give the quantitative criteria of reliability and prediction resource elements in the function of time. Analyzes the distribution function of the time life may present function hazard rate adequate historical data maintenance service Ukraine reinforced concrete bridges. We offer models based on accepted theory works distributed random variables.
