Geometrical nonlinearities on the static analysis of highly flexible steel cable-stayed bridges

Wang and Fu 1 STATIC AND STABILITY ANALYSIS OF LONG - SPAN CABLE - STAYED STEEL BRIDGES

The analysis based on an ideal state as well as the simulation and control to reach it are common issues in the design and construction of a cable-stayed bridge. For a long-span cable-stayed bridge, the huge initial stress accumulated in the pylon and the girder will reduce the overall structure stiffness. Thus, the live load evaluation employing influence lines, which is based on the Muller-Br...

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...

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...
