INTERIM REPORT. BRIDGE VIBRATION STUDY

This report describes the preparation and initial field testing of highway bridges in Indiana. The ultimate objectives of the study are the establishment and implementation of a practical bridge design technique which will directly regulate the dynamic response characteristics of bridge structures and the establishment of a reasonable set of design criteria for human tolerance to bridge motions. A representative sample of 60 bridges in Indiana were selected from a master computer file. The effects of a standard test vehicle in addition to the typical traffic loading were measured using accelerometers and reflection gauges. A survey of human response to the motion was conducted in conjunction with the testing. The values obtained were compared to see if similarities occurred within each bridge category. The acceleration frequencies were also checked against the human response values for similarities. From these comparisons 27 bridges were selected for further detailed examination. /FHWA/
