摘　　要：预应力钢棒张拉锚固体系强度高,具有良好的耐腐蚀和防火性能,被成功地运用于大型公共钢结构建筑中。研究表明,预应力钢棒体系能有效控制结构变形、增加结构刚度。开发国产预应力钢棒体系和张拉设备用于实际工程是完全可能和必要的。A tension and anchor system of prestressed steel bar has high strength, excellent fire and corrosion resistance, and has been successfully used in some large public steel structure buildings. It is indicated that a prestressed steel bar system can effectively control deformation of buildings and can increase stiffness of structures. It is necessary and possible to invent a domestic prestressed steel bar system and relevant tension devices which can be used in practical projects.
