Construction and Design of Cable-Stayed Bridges

Serviceability limit state of vibrations in under-deck cable-stayed bridges accounting for vehicle-structure interaction

Verification of the serviceability limit state of vibrations due to traffic live loads can be neglected in conventional types of concrete road bridges but becomes critical in the design of slender structures like Under-Deck CableStayed bridges. The novelty of the work presented in this article is that an innovative vehicle-bridge interaction model is employed, in which realistic wheel dimension...

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...

Structural Design of Cable-stayed Bridges

Cable-stayed bridges are extremely elegant and very effective structures and they are also architectural landmarks. The combination of multiple simple systems allows for a structure where the role of each of its components is well defined. When a cable-stayed bridge is chosen, the initial design phase is of utmost importance. The characteristics of the structure and whether if it is mainly cons...
