Effects of Long Wavelength Component of Roadway Roughness on Traffic Vibrations Caused by Heavy Running Vehicles

Abstract

Dynamic response analyses using 4-degree-of-freedom vehicle model were performed to investigate the effects of the long wavelength components on the traffic vibrations of highway bridges. The numerical results demonstrated that vibration caused by heavy running vehicles would be very dependent on the longitudinal profile of the long wavelength component which varied according to the vehicle speed.
