Shear loads perpendicular to slotted holes

Shear loads perpendicular to slotted holes

The European design guidelines for anchors (ETAG 001, Annex C for mechanical and ETAG 001, Technical Report TR 029 for chemical anchors) describe in section 4.2.2.1 the influence of slotted holes on the distribution of shear loads:
“Slotted holes in the direction of the shear load prevent anchors to take up shear loads. This can be favourable in case of fastenings close to an edge.”
