Abstract

A new method to identify moving loads on a beam using measured vibration responses is studied for its possible application to identify axle loads when applied to the real bridge/ vehicle interaction problem with road surface roughness and incomplete vehicle speed. Results from numerical studies on both a single and multi-span bridges and from laboratory experiment show that the method can identify individual axle loads travelling at non-uniform speed with small error. It can even identify the weight of the vehicle accurately when the vehicle brakes on top of the bridge deck. (C) 2003 Elsevier Science Ltd. All rights reserved.
