Simulation of Bridge Load Testing Process by Finite Element Model

Abstract

Almost of the bridges in Thailand, that have been built and used for more than 25 years, need to be assessed when the vehicle weight exceeds the legal limit. The Laksi Intersection Bridge was chosen as the case study because this bridge needs to support a heavy truck, which carried a huge guide way beam for construction of a part of the pink line monorail project. The objective of this research is to create a Finite element model (FEM) for simulation of the bridge load testing and transportation of Heavy truck. The finite element model needs to be accurate in terms of deflection and a short processing time. The results showed that the difference deflection between finite element model and field test were indicated in the criteria in this work. Therefore, these finite element models can be used for simulation of bridge load testing and transportation of heavy truck.
