Identification of variation coefficient of equivalent stress range of steel girders with cracks

Original language description

A steel bridge in operation is subjected to multiple variable stress range spectrum from the passage of axles of vehicles of different weights. The fatigue reliability assessment of steel bridges can be performed using the equivalent stress range, which is converted from the variable stress range spectrum. The paper presents a case study of the identification of the coefficient of variation of the equivalent stress range of steel girders. The histogram of equivalent stress range is statistically evaluated with consideration to uncertainties resulting from the statistical evaluation of the histogram of stress range spectrum from field monitoring. It is shown that the equivalent stress range can be rationally considered as a random variable with Gauss probability density function with coefficient of variation of 0.1. The case study is evaluated using the Latin Hypercube Sampling statistical method. The results are exploitable in the probabilistic analyses of reliability and lifetime of bridges using linear elastic fracture mechanics.
