EVALUATION OF AUXILIARY MASS DAMPER CONNECTED TO PEDESTRIAN BRIDGE. SECOND NATIONAL STRUCTURAL ENGINEERING CONFERENCE, ADELAIDE, 3-5 OCTOBER 1990; PREPRINTS OF PAPERS

Long span steel box girder pedestrian bridges are prone to excessive vibrations due to pedestrian loading. The introduction of auxiliary mass dampers on some of these bridges has reduced the vibration level, but the technique of their evaluation and "fine tuning" has been a mystery. It is possible to evaluate an auxilliary mass damper using a finite element model and on-site testing in order to reduce vibration levels. The technique to evaluate an auxilliary mass damper for a pedestrian bridge has been described in this paper. It used numerical analysis and field testing, and was simple and cost effective. Once the computer model has been prepared, evaluating other damping devices can easily be carried out without expensive on-site testing of each device. Final testing could be carried out to confirm the prediction from the numerical analysis. For the covering entry of the conference see IRRD 831067. (TRRL)
