PREDICTION OF LONG-TERM STRESS RANGES. USER'S MANUAL - STRESSES HISTOGRAM PREDICTION SYSTEM

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 description of two computer programs which operate as a system with BRGSTRS (Report FHWA-RD-73-44) is given. The first, SYNGEN, generates single axle loads for the BRGSTRS program, which in turm generates a stress signature curve for each axle load. The second, HISGEN, generates long-term stress range histograms from the single axle stress trace. Included are utilization and data preparation instructions and a sample case.
