随着社会经济的发展,预应力混凝土结构已越来越多地被应用于房屋、铁路、公路、能源、水利、电力等建设工程中,几乎没有不能用预应力来解决的结构问题,而且预应力往往能获得彻底革新结构的效果。就预应力混凝土结构在房屋建筑中的应用展开了系统的研究,并结合实例详细阐述了预应力混凝土结构在实际工程中的优点,主要表现在:减少钢筋用量和构建截面尺寸,耐久性好,节约材料,减小自重等。充分发挥预应力混凝土结构的优势,将有助于工程建设的开展,进而更好地造福人类。
With the development of society and economy, prestressed concrete structures have been increasingly used in construction projects such as houses, railways, highways, energy, water conservancy and electric power. There are few structural problems that can not be solved by prestressed concrete. Stress often results in a radical innovation of the structure. The application of prestressed concrete structure in building construction has been systematically studied and the advantages of prestressed concrete structure in practical engineering have been elaborated in combination with examples. The main features of the prestressed concrete structure are as follows: reducing the amount of reinforcing steel and building the sectional size, Save material, reduce weight and so on. Give full play to the advantages of prestressed concrete structure, will contribute to the construction of the project, and thus better for the benefit of mankind.
