The Bailey frame is a widely used bridge in the world, and the original Bailey Army Bridge was designed by British engineers in 1938. During World War II, the military steel bridge was widely used. After the war, many countries changed the Bailey steel bridge after some improvements to civilian use. Today, it plays an indispensible
role in the construction of transportation and flood fighting.
Bailey steel bridge adopted the prestressed steel structure, the so-called Bailey steel bridge prestressed steel structure, is people in the steel structure bearing system consciously introduced human stress to offset the load stress, adjust the peak internal force, enhance the structural stiffness and its stability, improve the structure of other properties and using the prestress technology to create a new system. Its main features are:
1. Fully and repeatedly uses the elastic strength amplitude of the steel, thus increasing the bearing capacity of its structure.
2. Improves the structural stress state and saves the steel. From the current situation, the prestressed structure can also save 30% of the steel.
3. Improves the structural stiffness and stability, and improves the various properties of the structure.
Prestressed steel structure can produce huge economic benefits, can save a lot of steel, reduce the comprehensive cost. The economy and structural system of prestressed steel structure, buss scheme and process, loads nature and strength, structural structure and node, the installation method and the material price and many other factors are related.
Under normal circumstances, the prestressed steel structure can save 10%~20% of the steel for once, and 20%~40% of the steel for many times. And the prestressed innovation system structure compared with the non-prestressed traditional structure to save steel several times to dozens of times. In conclusion, the greater the strength potential in structural materials, the higher the economic benefit of using prestress. For example, there is a lot of strength potential near the center of gravity axis of the solid belly beam section. The economic benefit of adopting prestress is much higher compared with that of lattice structure beam.
