• Abstract:
  Since its construction in the early 1960's, the three-quarter-mile-long predominantly reinforced concrete bridge structure on U.S. Highway 180 over the Hubbard Creek Reservoir in north central Texas has developed significant permanent deformation or sag near the center of most of the 40-foot-long simply supported pan girder type spans. This undulating profile tends to cause trucks operating at certain speeds to bounce and pitch rather severely and thereby produces dynamic loads that are more than 1.5 times the static weight of the vehicle. A computer simulation technique which was used to investigate the complex interaction between the existing road surface profile and representative heavy vehicles operating at various speeds indicated that the potentially damaging dynamic loads can be reduced to near static load levels by either keeping truck speeds below about 20 mph or by smoothing the bridge deck with an overlay.
