Abstract: Highway bridges are idealized as beams as well as orthotropic plates. A standard HS - 20 - 44 highway vehicle is represented by a planar, two axle, sprung mass system with frictional device. The response equations are derived in terms of the natural modal coordinates of the bridge and of displacement coordinates of the vehicle. The bridge dynamic loading due to vehicle braking is investigated for symmetric as well as eccentric loading of vehicle.
