The report presents results of an investigation involving the measurement of strains produced by truck traffic on eight selected highway bridges. The development of a sampling procedure is described along with the instrumentation used. Results are presented in the form of Stress - Frequency distributions, and are compared with the commercial truck traffic volumes and gross weights. Some studies involving loading with a controlled test vehicle are also reported. Based on certain assumptions and results of laboratory structural fatigue tests by others, the life expectancy of the eight bridges is determined. The major conclusion of the study is that apparently there is no great danger of fatigue damage to the bridges tested under loadings presently allowed in Michigan. (Author) BPR Abstract
