Highway Bridge Vibration Studies
The general objectives of this research have been to obtain a better understanding of the dynamic performance of highway bridges and of the vibrations sensed by bridge users in order to aid in the development and implementation of a dynamic-based design criterion which can more effectively ensure the comfort of pedestrians, maintenance workers, cyclists, etc. Because the human body is primarily sensitive to changes in motion, the investigations have focused on accelerations. Special purpose computer programs were used for parametric studies of the bridge vehicle system. Significant parameters were found to be span length, weight and speed of the vehicle, and the roughness of the bridge deck. Maximum accelerations were only moderately increased by reductions in girder stiffness. Dynamic responses of some 62 steel and concrete beam bridges under actual highway traffic were measured in the field. Bridges were instrumented with midspan accelerometers and one deflection transducer, all mounted on the curbs of the deck. Differentiated deflection records were used to check corresponding acceleration records.
