| 摘要： | The purpose of this research is to study the influence of different construction materials on the dynamic impact factor of bridges. Initially, introduction of the dynamic impact factor and some evaluation methods are presented. A comparison of the regulations of bridge codes from some countries is made. Then, from a simply supported Euler-Bernoulli beam, the evaluation model used in this paper will be considered. A numerical example is shown with a constant vehicle loading substituted into the model using three different materials of bridge systems. The results of the models show the effect of different materials on the dynamic impact factor. This report introduces a simple method for evaluation of changes in the dynamic impact factor, which will be useful to practitioners and students who are interested in the subject. |
