Column splices ends prepared for contact in bearing

Column Flange

25 Column splice — ends prepared for contact in bearing

Splices should be designed for full contact bearing to resist the vertical loads. In addition, the following recommendations should be followed:

(a) the projection of the flange cover plates beyond the ends of the column members should be equal to the width of the flange of the upper column or 225 mm, whichever is greater

(b) the thickness of the flange cover plates should be half the thickness of the flange of the upper column or 10 mm, whichever is greater

(c) when the column sections to be joined are of the same size, then nominal web cover plates may be used

(d) when the column sections to be joined are of different sizes, then web cleats and a division plate should be used to give a load dispersal of 45°.

It should be noted that these splices may have to be designed to resist moments and/or tension because of robustness considerations. In these cases, the permissible shear value of the bolts may have to be reduced, and the tensile capacities of the division and flange plates should be checked.
