Abstract

A fatigue reliability analysis is performed for steel girder bridges. The data base for the live load model is obtained by weigh-in-motion (WIM) measurements. Bridge structures were selected to determine the site-specific truck parameters and component-specific stress spectra. Stress cycles are presented as cumulative distribution functions. The WIM measurements confirm a significant variation in stress spectra between girders. Fatigue limit state function is developed using the number of cycles to failure as the structural resistance, and the number of applied cycles as the load. The statistical parameters of steel are based on the available test results. Reliability indices are calculated for several equivalent stress ranges.
