Vehicles Loads Influence on Box Girder Bridges

Box girders bridges are widely used in modern highway systems because of their efficiency and attractive appearance. Vehicles loads represent one of the mainly factors that influence the structure reliability of the box girders bridges. Calculation of bridge resistance with different stress due to vehicles loads as close as possible to the real ones constitute the premise of a correct design of the structure. The goal of this study is to realize a description regarding the behavior of box girders bridges analyzed under different vehicles loads conditions. Nowadays the finite element methods (FEM) are highly used because of their capacity to simulate and evaluate the structure efficiency of bridges. By highlighting where the maximum stress values appear we will help the constructor to avoid dangerous sections. Based on this study, we will outline future research directions, aiming to identify and improve the mechanical and strength characteristics of box girders bridges.
