A SIMPLE ANALYSIS OF THE EFFECT OF CONSTRUCTION MATERIALS ON BRIDGE IMPACT FACTORS

This research considers the influence of different construction materials on the dynamic impact factor of bridges. The general concept of the dynamic impact factor and typical evaluation methods are reviewed. A comparison of bridge codes from some countries is made. A simply supported Euler-Bernoulli beam is used to evaluate influence of materials on the impact factor. A numerical example is shown with a constant vehicle loading substituted into the model using three different materials for the bridge system. Interesting results from the model suggest that the choice of construction material is a secondary factor in the dynamic impact factor. A large number of other factors can be evaluated in the same manner to determine which design parameters have the greatest influence on the dynamic impact factor. The simple method for evaluation of changes in the dynamic impact factor is expected to be useful to practitioners and students who are interested not only in the influence of material selection, but also on the other factors, such as pavement roughness.
