预应力钢结构的经济效益如何？发布时间：2015-9-19 9:51:33 浏览次数:705
Economy and structure system of prestressed steel structure category, bousso plan and process, the nature of the load, and the strength, structure and node, installation method and material price, and many other factors.
Under normal circumstances, the prestressed steel structure than the traditional steel structure using a single prestressed can save 10% ~ 20% of steel; Several times with prestressed steel can save 30% ~ 40%. Compared with the traditional structure and the innovation system of prestressed structure to save more than 50% or more steel. In short, the bigger the potential strength of structural materials, the use of the economic benefits of prestress is higher. For example, in the plain girder cross section near the center of gravity axis of strength potential, and the economic benefit after adopting prestressed lattice beam is much higher compared to the same.
