Nonlinear Structural Design Optimization of Cable Stayed Bridges

ABAQUS Finite Element Analysis software is used to apply computational design optimization process on cable stayed bridge models in relation with shape and topology of the structure. Three styles of stay cables arrangements and three types of pylons are created for structural optimization. The aim is to identify the most efficient design models with a robust, serviceable, safe and stiffness against oscillation and failure due to self weight and external loads
