is intended to account for severe consequences of single element failure; categorisation of
elements according to the table above should consider redundancy of elements accordingly.
11.4.2
The consequence factors shown in Table 11-1 shall be applied based on the calculated lift point loads
after consideration of all the factors shown in Sections 5.2 through 5.8. If a partial load factor design is
used then the consequence factors in Table 11-1 shall also be applied to the partial load factors for
structural design. Consequence factors in Table 11-1shall also be applied to lift point lateral loads.
11.5 LIFT POINTS 11.5.1
An analysis of the lift points and attachments to the structure shall be performed, using the most
severe load resulting from Section 11.2 and all the factors as appropriate from Section 5.
11.5.2
Where the lift point forms an integral part of the structural node, then the lift point calculations shall
also include the effects of loads imposed by the members framing into the lift point.
11.5.3
Where tugger lines are attached to lift points their effect shall be considered in the lift point design.
11.5.4
The design of the lift points should consider the design requirements for additional loads, geometrical
requirements etc. given in Section 12.
11.5.5
NDT requirements for lifting points are given in Section 12.7.
