PREDICTION OF LONG-TERM STRESS RANGES - STUDY REPORT

The development of a computer simulation program system for generating highway traffic crossing a bridge and calculating the resulting stresses and stress ranges is described. The total system consists of four stand-alone programs which can be used either independently or as a dependent series where output from one program is used as input to the next. Output consists of loading and stress range histograms. A summary of all work performed and a description of each of the developed computer programs is presented. Included is a discussion on methods employed in the development including the stress calculations, the traffic generator, the preparation of stress histograms, results of a sensitivity or parameter study, and deficiencies in the methods of analysis. Comparisons of predicted and experimentally measured results are given. /FHWA/
