Paper Abstract

With the increment of the duration of service, traffic volume as well as the overloaded and overweighed vehicles cause serious damage to some early constructed expressways, and make the road condition getting worse. Thus, the expressways have been transforming from massive construction to upgrading and regenerational time. Based on the inspection data of all bridges on some expressway, a rectangular slab bridge was modeled and beam's crack causes were analyzed by ANSYS. As a result, the deficiency in transverse reinforcement was the main cause of the longitudinal cracks in the reinforced concrete bridge beam. It is shown that the strength has been increased significantly by the application of bonding steel plate on the bottom of the bridge beam. The present study provides a valuable example for further reference on the design, monitoring, as well as strengthening the bridges of similar type.
