What are the advantages of cable-stayed bridges
Jul 10, 2021
1. Large span and small building height
The comparison of the bearing internal forces and deformations of continuous beam bridges and cable-stayed bridges shows that due to the multi-point elastic support provided by Lasu, the bending moment and deflection of the main girder are significantly reduced, and the spanning capacity of the cable-stayed bridge is greatly enhanced.
2. Reasonable force
No bridge type can evolve into a variety of shapes like a cable-stayed bridge. Due to the diversity of the combination of towers and plain beams, it provides a wide range of changes for the design concept, which can adapt to a variety of different use requirements and natural conditions of the bridge site.
3. Convenient and safe construction
The cantilever construction method is a commonly used method for cable-stayed bridges. It is especially suitable for large-span cable-stayed bridges with a large clear height. In the construction stage of the arm construction, the effectiveness of the stayed cables should be fully utilized to minimize the load-bearing capacity of the hanging basket: through cable force adjustment Even and reasonable force on the main beam is an important measure to ensure economy and safety.
4. Large rigidity.
Compared with the suspension bridge, the cable-stayed bridge has greater vertical stiffness and torsion stiffness, good wind-vibration stability, and no large anchors, so it is within the applicable span range. Although the wind dynamic performance of the cable-stayed bridge is good due to its structural rigidity. The frequency of torsion and vertical bending is higher than that of suspension bridges. However, it cannot be ignored in areas with strong winds, large spans and small bridge widths.
5. Beautiful bridge
The combination of high towers, strong cables and light main beams, like a graceful harp and sailing sails, fully reflects the high harmony of power and beauty of contemporary bridges. At present, the majestic and elegant tower-pier-consolidated floating system is comparable to the robust and upright tower-beam-consolidated single-cable surface system.
