CONTROL OF TRAFFIC-INDUCED VIBRATION IN BUILDINGS USING VEHICLE SUSPENSION SYSTEMS

Various corrective measures are usually suggested for reducing the lev els of traffic-induced vibrations in buildings, e.g. road rehabilitati on, speed control, soil improvement, the use of building isolation sys tems, etc. Although some of these measures are effective, they are in most cases difficult to implement and/or expensive. In view of recent measurements of vibration levels at several sites in Montreal, it appe ars feasible to significantly reduce vibration induced by transit buse s (the cause of the majority of traffic vibration complaints in that c ity) by modifying the characteristics of their suspension systems. Mod ifications would be made to achieve either a small axle hop amplitude or an axle hop frequency that is below the lowest site cutoff frequenc y in the city. In addition to these results, a description of test veh icles, field tests, and measurement and analysis procedures are presen ted. Published by Elsevier Science Limited.
