✦ Synopsis

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.
