1. Flat anchorage can be used to anchor PC strand which strength below 2000Mpa.
2. Flat anchorage has excellent static load anchoring performance. Anchoring efficiency factor is ηA≥0.95 and elongation εa≥2% , and meet International strandard FIP 1993<Post tensioned prestressing system acceptance advice>
3. concrete slab has excellent fatigue resistance. It pass 200 million fatigue resistance test which stress amplitude is 120MPa, and the upper limit of stress is 0.65fpk.
4. Flat anchorage has good self-anchor performance
5. The draw-in of anchor is ≤6mm.
6. The friction loss of anchor is ≤2.5%
