Design Optimization of Bridge Deck using Response Surface Optimization Technique

Box girder bridges have been used extensively in various parts of the world and are commonly used for highway and railway bridges, pedestrian bridges, and cable-stayed bridges. The objective of current research is to evaluate the structural characteristics of box girder bridge using techniques of FEM. The modelling and simulation of box girder bridge is done in ANSYS simulation package. The critical regions which are subjected to damage is identified. The FEA simulation results have shown that the maximum deformation is observed at the center of the box girder bridge structure. The deformation is maximum at the center of the load application region. The shear stress is obtained to be maximum at the corner support edges and regions of box girder bridge.
