Analysis of the Current State of Metal Runways of Railway Bridges

Abstract

Purpose. The purpose of this work is to analyze the current state and accident rate of metal span structures of railway bridges. Methodology. Data collection of emergency events on artificial structures. Studying the experience of accident of metal bridges for taking lessons that will help to eliminate the causes that caused them. Findings. The result of this work is the collected data on the state and accident of artificial structures of various sources. Originality. The scientific interest is that with sufficient experience in the construction and operation of artificial structures, the use of modern technologies and materials at this time of bridge crash is not a rare phenomenon. Therefore, the experience of accidents in artificial constructions should be studied, analyzed and used in future decisions. Proving that a probabilistic approach can be used in calculations, as well as the application of norms Eurocodes – this is a possible way to address the question of legitimizing the probabilistic approach. Practical value. Based on the data obtained, it is possible to conclude that the factors of the loss of stability of the individual elements of construction and the fatigue of the materials have not been sufficiently studied, the fatigue properties should be investigated, in order to draw conclusions derived from the experience of bridges in order to help eliminate the causes that caused them.
