Application of Influence Lines on Static Analysis of Cable-Stayed Bridges

Non-Linear Analysis of Cable Stayed Bridges

he concept of cable-stayed bridges dates back to the seventeenth century. Due to their aesthetic appearance, efficient utilization of material, and availability of new construction technologies, cable-stayed bridges have gained much popularity in the last few decades. After successful construction of the Sutong Bridge, a number of bridges of this type have been proposed and are under constructi...

DESIGN OPTIMIZATION OF CABLE-STAYED BRIDGES USING MOMENTUM SEARCH ALGORITHM

Design optimization of cable-stayed bridges is a challenging optimization problem because a large number of variables is usually involved in the optimization process. For these structures the design variables are cross-sectional areas of the cables. In this study, an efficient metaheuristic algorithm namely, momentum search algorithm (MSA) is used to optimize the design of cable-stayed bridges....

Motion Based Design of Cable-Stayed Bridges

Recent increases in limit spans of cable-stayed bridges have highlighted the need for new concepts in analysis and design. The increased flexibility requires more theoretical studies on non-linear behavior and on dynamic analysis. Design also is more oriented to a performance-based approach: motion control is more important than strength analysis. My main objective is to define what are the par...

Construction and Design of Cable-Stayed Bridges

Three examples of flutter analysis of cable-stayed bridges

There are multiple configurations permitted for a cable stayed bridge such as the number of spans, tower shapes, and cable arrangements. Therefore it is always important to study the behaviour of these types of structures against strong winds so that aeroelastic instabilities do not appear. This paper contains detailed aeroelastic analyses of three cable stayed bridges of very different configu...
