A compression strut comprises a central tubular section with a threaded taper connection welded at each end.

The taper connection is assembled with a threaded fork/pin end connection and threaded lock cover. The threaded fork end connection enables the compression strut to be adjusted in length. The nominal strut adjustment length is +/- 50 mm.

The tapered lock cover and machined cone conceal the threads.

The installed compression strut is fixed to the final length by use of a grub screw set into the cone.

The strut system is designed in accordance with EN1993-1-1 and EN1993 -1-8 and their respective UK National Annexes. The ultimate capacities quoted take account of self-weight bending of the strut in accordance with equation 6.10, Table NA.A1.2(B) UK National Annex to EN1990.

Critical Sections:-

1, CHS verification

• Section capacity (combined bending & axial)

2, Interface between CHS & welded cone

• Weld size required

3, Threaded bar

• Combined bending & axial

• Axial resistance of thread

4, Fork

• Combined bending & axial

5, Pin

• Combined bending & shear

NB: Reference to 'bending' above means the summation of strut buckling and self-weight bending effects.

All material factors are as the UK National Annex.
