Research on Carrying Capacity Evaluation of some Reinforced Concrete Bridge under the Special Type Load

With the development of social economy, the traffic burden is increasing, and many bridges appear damage at different degree because they have been overloaded. There are many special type loads beyond specification range in the overloaded vehicles, however the carrying capacity evaluation of the bridge under the special type load is different from the conventional methods. Take the reinforced concrete bridge built in the 90's of the 20th century for example, this paper analyses and discusses the existing carrying capacity evaluation method of the bridge when the special type load beyond the design standards drives on the bridge, as well as the whole process of analysis, loading, and the results analysis of the loading test in detail. Finally, the results of the study have a high guiding significance to the similar work.
