Zielsetzung und Themenschwerpunkte (Objectives and Key Themes)

This research aims to optimize the shape and topology of cable-stayed bridges using nonlinear design optimization techniques. This is achieved by employing ABAQUS finite element software to generate various bridge models with different stay cable arrangements and pylon shapes. The research explores the structural behavior of the cable-stayed bridge under static loads, analyzing responses such as reactions, deflections, and Mises stresses in key components.
