Construction and Design of Cable-Stayed Bridges

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...

Active Tendon Control of Cable-stayed Bridges: Theory and Implementation

This paper presents a strategy for active damping of cablestayed bridges, using active tendons. The first part of the paper summarizes the theoretical background: the control law is briefly presented together with the main results of an approximate linear theory, which allows to predict the closed-loop poles with a root locus technique. The second part of the paper reports on experimental resul...

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...
