体外预应力结构体系是指对布置于原有混凝土结构或其他结构之外的钢索施加预应力所形成的预应力结构体系,它既可用于预应力混凝土桥梁、特种结构和建筑工程结构等新建结构,也可用于旧有的钢筋混凝土结构和预应力混凝土结构的重建、加固和维修。1体外预应力加固的优点 (1) 由于钢绞线自身材质的特点可采用连续跨处理,加强了结构的
External prestressed structural system refers to the prestressed structural system formed by prestressing the steel cables placed outside the original concrete structure or other structures, which can be used for new construction of prestressed concrete bridges, special structures and construction engineering structures Structure, but also for the reconstruction, reinforcement and repair of old reinforced concrete structures and prestressed concrete structures. 1 The advantages of external prestressed reinforcement (1) Due to the characteristics of the strand itself can be used continuous material handling, strengthening the structure
