Trial test to determine the permissible load, based on DIN 4125
Suitability test
➤ On every building site, test at least 3 anchors at a location where unfavourable results may be expected.
➤ Load these test anchor-points until they fail, but not to more than max. 220 kN.
➤ The permitted anchor force is determined from the load at failure with a safety factor of 1.5.
|
Permitted capacity of the tie-rod to DIN 18216: 160 kN Specimen calculation: ▪ Failure load: 160 kN ▪ Permitted anchor force: 160 kN/1.5 = 106.7 kN |
➤ With reference to the permitted anchor force, space out the anchors and determine the anchor force actually encountered (e.g. 100 kN).
