Closing remarks at symposium on bridges : loading history, ultimate strengths, and performance. Paper presented at the 51st Annual Meeting of the Highway Research Board HRB, Washington, D.C., January 1972.

The one recurring theme from all of the papers presented at the symposium was that measured stresses were small and well below the live-load design stresses, and that therefore, there is no need to be concerned about fatigue problems in highway bridges.
