Agt: Key Factor of High Quality Self Drilling Anchor
Agt: Key Factor of High Quality Self Drilling Anchor
Some Concepts:
1. The brittleness of hollow bar anchor is independent of its strength, but related to the ductility.
2. A and Agt (Elongation rate after break and elongation rate at max load) are not included in design index, but they are very important to security.
3. Hollow bar anchors with same specification and strength, the Higher Ductility (Agt) one can absorb 2 to 3 times damage energy while fracture process.
4. High Agt value = high ductility = high security.
5. Security is demanded in all civil engineering, and the key factor of safe self drilling anchor is ductility (Agt).
6. The material standards of soil nails and micropiles in Europe and US have been released, and Agt is one of required indexes.
