Abstract

Stresses in three steel highway bridges under usual traffic loads were recorded and classified using the rain-flow counting method. The statistical evaluation of stress ranges provided an empirical formula where the number of heavy vehicles per day and the span of the investigated bridge element are the most important parameters. The formula presents the stress spectra, i.e. the tables of the number of stress ranges in various stress classes which may be applied to the design of steel bridges for fatigue.
