COMPARATIVE STUDY ON DIFFERENT MODELING TECHNIQUES FOR CABLE- STAYED BRIDGES AND THEIR EFFECT ON THE STRUCTURAL BEHAVIOR UNDER STATIC LOADS

Abstract

This thesis discusses in detail the structural components of cable stayed bridges and the optimum way for modelling them. It presents different methods of modeling a cable stayed bridge to know which model is optimum and is more representative for the bridge. Aswan cable stayed bridge is considered as a case study and modeled by two different methods: spine model and shell model First, the shell model is adjusted by applying a set of modifications to represent the spine model behavior. Second, and a detailed shell model that has no modifications is then created. Third, a detailed comparison between models is carried out. The comparison included cable pre-tension force and deck straining actions
