Anchoring details – General

Decisive for the choice of tie
rod are the forces that occur at
the anchor point of the support
frame. Anchoring can be per-
formed as follows:

With tie rod DW 15

(Fig. 19.1) and M cross stiffener
44.

With tie rod DW 20 or

DW 26.5 and twin channel 80/22
or 245/22 (Fig. 19.5).

With anchor loop 15

(Fig. 19.2) or 20 and twin
channel (Figures 19.3 and 19.4)
or with anchor loop 15 or 20
turned through 180° (Fig. 19.4).
Contact the structural engineer if
additional rebars are required.

Maximum anchoring loads:
Tie rod DW
DW 15 = 90 kN per tie rod
DW 20 = 160 kN per tie rod
DW 26.5 = 250 kN per tie rod

Anchor loop
DW 15 = 180 kN
DW 20 = 320 kN
