UTILIZATION OF STRESS HISTORY DATA IN BRIDGE DESIGN

David W. Goodpasture

Open publisher page 1 citations

Abstract

A method for checking the adequacy of steel stringer highway bridges for fatigue is presented. Truck types and weights are utilized with stress analyses to predict the fatigue life of bridges. The distributions of truck weights, axle weights and truck types were based on recent field measurements. A simplified method of establishing stress ranges due to typical trucks is summarized and an example is presented. However, any method may be used to obtain the stress ranges and the procedure outlined in the paper may be used. The method may be used in design or in checking existing bridges. /Author/
