STOCHASTIC APPROACH FOR EVALUATION OF RELIABILITY AND RESIDUAL LIFE OF TRANSPORT STRUCTURES
Published 2014-10-01“…Such approach for operated structures looks rather ivory-towered because the actual transport loads have a large statistical dispersion, they are characterized by periodicity, dynamic character, they can criss-cross structures and change in time as in short- so in long term prospects as well.Introduction of СТБ ISO 2394-2007 “Reliability of construction structures” on the territory of Belarus has provided an opportunity to pass from deterministic approach on evaluation of reliability and technical state of operated structures that considers virtual impact of substitute design loading on a real structure to probability approach that considers impacts of actual loadings in specific period of time and which can be determined with the help of experiments. Application of reliability parameter as a criterion of transport structure residual life which is determined with the help of probability method will make it possible to improve significantly the evaluation accuracy due mathematical precise accounting of peculiar features pertaining to actual impacts on specific transport structure and thus it will bring criteria for evaluation of transport structure residual life in accordance with the world development level of construction science and technology.…”
