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...

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...

Elastic-plastic Seismic Behavior of Long Span Cable-stayed Bridges

This paper investigates the elastic-plastic seismic behavior of long span cable-stayed steel bridges through the plane finite-element model. Both geometric and material nonlinearities are involved in the analysis. The geometric nonlinearities come from the stay cable sag effect, axial force-bending moment interaction, and large displacements. Material nonlinearity arises when the stiffening ste...
