● The values are suitable for: correct installation, no influence of spacing and edge distance, minimum base material thickness.
● All the data applies in C20/25 concrete base material. If the base material grade changes, the corresponding concrete influence coefficient will needs to be increased.
● The * part in the table is steel failure control.
● The material of all the anchors in the table is alloy steel, grade 8.8.
● Design load: including material partial factor, but not including overall partial factor.
● Recommended load: including not only material partial factor, but also including overall partial factor 1.4.
● If your NJMKT Dismountable Anchor(Mechanical Anchors) with special material and specification is not listed in this table, please contact our engineer for advice.
● All basic anchor data in this table is given according to 2013 ETAG001 and Appendix. The partial factor in the load application must be in accordance with national regulation.
