1903/2015 11Supplementary remarks - The main beam must have adequate fork support and be able to withstand torsion. - Values shown in the table are for one pair of fasteners. For multiple pairs, the table values F1,Rk () must be multiplied by the factor nef = (the number of pairs)^0,9 and table value F2, Rk must be multiplied by the number of pairs. - Appropriate action must be taken to ensure adherence to the insertion angle (assembly angle) and the connection geometry. - In the case of intermediate values of horizontal projection angle β, linear interpolations may be made. - Load-bearing values are applicable to the total effective length of each thread section. All calculations must be verified and signed off by the planner in charge before the work is performed.
