Synopsis

Scientific Study from the year 2013 in the subject Engineering - Civil Engineering, grade: -, University of Weimar, course: Cable Stayed Bridges, language: English, abstract: In this research, many models of a cable stayed bridge were generated using ABAQUS finite element commercial software for the purpose of proceeding with nonlinear design optimization on the shape and topology of the structure. The cable stayed bridge models in all cases are with a constant length and width for the deck, also the pylons height under and above the deck is constant, but the shape of stay cables arrangement varies to three main famous arrangements which are Fan, Semi harp and Harp.In addition to change in the pylons shape which are three known shapes Double out, Single Center and Single inclined out, and it is worthy to mention that in all cases of the shape optimization of the pylons, the stay cables arrangements are Fan style, andby governing computational nonlinear optimization process on the finite element models in all cases of shape and topology optimization through using static general step for analysis and a certain meshing type with global seeding size for the Beam elements, with a fixed and pinned boundary conditions for the deck supports and fixed boundary for the pylons.Concentrated static loads assigned on the same positions on the deck for all models cases.

A propos du livre

Présentation de l'éditeur

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
