Effects of bridge deck roughness on the dynamic response of single span bridges

Auther : J. AL-DUAIJ, M. ABDEL-ROHMAN AND R. JAMES PAYAPPILLY

 Department of Civil Engineering, College of Engineering & Petroleum, Kuwait University, P.O. Box 5969, Safat 13060, Kuwait

ABSTRACT

A single span simply supported beam model is used to investigate the maximum acceleration and maximum deflection responses of single span bridges due to a moving vehicle. The vehicle is modeled as a single degree of freedom sprung mass moving with a constant speed. The dynamic responses of the beam due to varying the natural frequency, damping ratio, unevenness height and length, vehicle speed, weight and spring stiffness are studied. The effect of each parameter is shown and analyzed. Recommendations are given for consideration in real life practice.
