| 摘 要： | 通过对直线布筋的12根缓粘结钢绞线和不同转角的15根缓粘结钢绞线的张拉试验研究,测得每根钢绞线的摩擦损失大小,根据钢绞线长度和转角大小,计算出在给定缓粘结剂配方下,缓粘结预应力钢绞线摩阻系数κ、μ的大小和离散程度,为缓粘结预应力混凝土结构设计与施工提供了参考。

| Abstract: | Through experimental study of 12 retard-cohesive prestressing strands of straight line and 15 retard-cohesive prestressing strands of different angles,the friction loss of each strand is obtained.The friction coefficient κ and μ and the separate degree of the retard-cohesive prestressing strand have been figured out,which provides a reference for design and construction of retard-bonded prestressed concrete structures. |
