Relation of the Infrasound and the Bridge Vibration Generated by the Vibration of Moving Trucks
At the houses near the bridge , there have been complaints about a rattling sound and/or complaints about mental and physical discomfort caused by the infrasound , which is radiated from the highway bridge under moving vehicles. General trucks in Japan with rear leaf suspension have fre -quencies of about 3 Hz. Also,the frequencies of the tire spring vibration are about 10-20Hz. The steel continuous bridges with middle span length have the vibration modes with the same phase in each span and with the secondary mode shape. These bridge vibration modes are related to the suspension spring vibration and/or the tire spring vibration of the trucks. This study clarifies the relation of the infrasound ,the vibration of the trucks ,and the bridge vibration by using several experimental results.
