10 03/2015 11 WR Principles of design Load-bearing capacity values WR-T ETA-12/0062 lef = actual thread length in structural component hmin = minimum height of structural component – Values apply to connections where half of each fastener is in each structural component. – Connection geometry as shown in the drawings must be complied with. – Calculation of design values as shown in the box to the left of the tables. – All calculations must be verified and signed off by the planner in charge before the work is performed.
