AN EVALUATION OF BRIDGE VIBRATION AS RELATED TO BRIDGE DECK PERFORMANCE

THIS INVESTIGATION OF CONCRETE BRIDGE DECK DETERIORATION WAS MADE IN TWO PHASES: (1) A SUMMARY AND (2) THREE ASPECTS OF CONCRETE BRIDGE DECK CONSTRUCTION AND BEHAVIOR AS RELATED TO DETERIORATION. FIVE BRIDGES WERE OBSERVED UNDER CONSTRUCTION WITH CERTAIN MEASUREMENTS BEING MADE INCLUDING THE THICKNESS OF THE DECK, COVER OVER REINFORCING BARS, TEMPERATURE, HUMIDITY AND WIND VELOCITY. TWO TYPES OF PACHOMETERS WERE COMPARED. SIX WERE OBSERVED WHILE SUBJECT TO NORMAL TRAFFIC FOR A PERIOD OF NINE MONTHS. ALL OF THE BRIDGES EXPERIENCED AN INCREASE IN TRANSVERSE CRACKING DURING THIS PERIOD BUT ESSENTIALLY NO CHANGE IN THE FREQUENCY OF THE FUNDAMENTAL MODE OF VIBRATION WAS NOTED. AN INCREASE IN THE AMOUNT OF TRANSVERSE CRACKING WAS SIGNIFICANTLY NOTED IN THE NEGATIVE MOMENT REGIONS. THE REMAINING SIX BRIDGES STUDIED WERE SUBJECTED ONLY TO CONSTRUCTION TRAFFIC. FROM THIS OBSERVATION, CONSTRUCTION TRAFFIC HAD A DETRIMENTAL EFFECT ON SEVERAL OF THE BRIDGES. /AUTHOR/
