预应力混凝土摩擦损失计算方法的改进建议

IMPROVING SUGGESTION ON CALCULATION METHOD OF FRICTION LOSS IN PRESTRESSED CONCRETE STRUCTURE

通过对预应力混凝土摩擦损失的两个关键因素———摩擦系数κ和 μ的深入分析 ,指出现有计算方法的不足之处 ,并提出相应的改进建议。

Through an analysis of friction coefficient κ and μ——two key factors of friction in prestressed concrete structure,the shortage of current calculation method is pointed out and corresponded improving suggestion is put forward as well.
