部分有粘结预应力混凝土结构技术应用研究

Partial Bonded Prestressed Concrete Structures Technology Application Research

通过对某新火车站候车大厅部分有粘结预应力混凝土结构施工技术应用介绍,说明使用有粘结预应力混凝土结构,大幅度提高了结构跨度,减少了结构截面尺寸,使构件的延性得到了提高,控制了结构的裂缝与变形,减小裂缝宽度,有利于结构抗震。与此同时该项技术与全预应力相比简化了张拉、锚固等工艺,节约了钢材,降低工程成本。

Through partial bonded prestressed concrete strucutres technology application of a new railway station,illustrates that the use of bonded prestressed concrete structure can greatly improve the span,reduce the structure section size,make the ductility of the member improved,control the cracks and deformation of the structure,decrease the crack width,which is beneficial to structural seismic. At the same time the technology compared with the whole prestressed simplifies the tension and anchorage,save steel,reduce engineering cost.
