预应力技术在建筑工程中的应用

Application of Prestress Technology in Building Engineering

预应力技术是当今土木建筑领域一项十分重要的新技术,因其经济性和便捷性在大跨、重载以及超长结构中广泛应用。现行规范在正常使用阶段对预应力结构要求比普通结构严格,预应力结构的耐久性更好,承载的安全储备更高、结构安全性更好。文章简要阐述预应力技术在各种结构体系中的应用,为业主和设计师在确定建筑方案时提供一种可能,也为结构工程师确定结构方案时提供一种选择。

Prestressed technology is a very important new technology in the field of civil construction.Because of its economy and convenience,it is widely used in long span,heavy load and super long structure.In the normal use stage,the current code has stricter requirements on prestressed members than ordinary structures.The durability of prestressed structures is superiority,the bearing safety reserve is higher,and the structural safety is better.This paper briefly described the application of prestressed technology in various structural systems,which provides a possibility for the owner and designer to determine the architectural scheme,and also provides a choice for the structural engineer to design the structural scheme.
