Performance Enhancement of the Existing Bridges due to Overweight Vehicles with Multi-Axle Loading

Abstract:

This article presented the analytical results focused on the responses of existing bridges in Thailand subjected to overweight vehicles. The bridges, span lengths ranging from 5 to 20 meters, were loaded by the overweight vehicles with multi-axle loading having gross weight of 400 tons. The rating factors of bridges were also performed. The bridge strengthening methods using carbon fiber reinforcement polymers and intended settlement technique were also presented.The results indicated that the load rating factors were increased and conformed to the load rating standards. The results of this study would be a reference data to establish an alternative plan of bridge strengthening to improve the safety of the bridges under a moving of overweight vehicles.
