EFFECTS OF VEHICLE BRAKING ON THE DYNAMIC LOADING OF BRIDGES

An experimental and analytical study of the effect of vehicle braking on dynamic loading of single span highway bridges has been completed. Static and dynamic tests were conducted to measure the tyre and suspension characteristics of a light two- axle truck which was later used as the load unit for dynamic tests on a bridge. The dynamic properties of the truck were determined from a numerical simulation of these vehicle dynamic tests. Bridge dynamic bending strains and vehicle acceleration and response were measured for bridge test runs with the vehicle travelling at constant speed and with the vehicle undergoing braking. Corresponding computer simulations were made, based on the measured system properties, and the results compared. (Author/TRRL)
