There is much prestressing loss for friction resistance among wedge, steel strand and anchor-ring in engineering.
预应力张拉施工中夹片、钢绞线和锚环之间存在着很大的摩擦阻力。
To avoid slip of CFRP bars, the friction angle between soft metal pipe and CFRP bars should be larger than the sum of barrel's conical angle and friction angle between wedge and barrel.
为保证碳筋不出现滑移，软金属管和碳筋间的摩阻角应大于锚环锥角和夹片与锚环之间的摩阻角之和；
