3 Terms and definitions
Inthis document the following terms and definitions apply
3. 1 anchorage a kind of anchoring and connecting equipment which is connected firmly at the end of a steel strand, and external tension can be transferred to the steel strand through it. 3. 2 zinc-5%aluminum-rare earth alloy-coated there are two anchorages installed at both ends of the zinc-5% aluminum-rare earth alloy -coated steel strand, which are components that can bear tensile load through loading the axial pre-stress in building engineering. 3. 3 pre-tensioning loading or unloading within the range of prescribed force values ,which makes elongation reading of the steel strand in a constant state. 3. 4 over tensioning the stretching with over designed force value is conducted on the cable, to make it keep in a stable and reliable state 3. 5 outward displacement the distance (/,) ofarelative displacement produced between steel strand and anchor under axial tensile force,/=/-/o
