Summary
:
The concern for the riveted steel truss was fatigue related as the structure was well above 100 years old, although no visible damage was detected. Monitoring with strain gauges at fatigue prone locations was carried out for one year. The measurement system was verified and the structural model was calibrated through load testing with known axle loads.
