Detailing of bolts, welds and anchors according to Australian standards

Bolts

Minimum pitch (distance between centres of bolt holes) shall not be less than 2.5 times the nominal bolt diameter. The value is recommended in Clause 9.5.1 and is editable in Code setup.

Minimum edge distance (distance between centre of the bolt hole to the plate edge) shall not be less than 1.25 times the nominal bolt diameter. The value is recommended in Clause 9.5.2 for rolled edges and can be modified in Code setup.

Welds

Minimum size of a fillet weld is checked according to Clause 9.6.3.2 and should be the lesser of the thinner part joined thickness and the value in the following table:

The weld size is assumed as \( \sqrt{2} \) times the weld throat thickness.

Anchors

Minimum spacing between anchors should be s ≥ 4d where d is nominal diameter of the anchor. The factor 4 is editable in Code setup.

Minimum edge distance follows the rules for bolts, i.e. it shall not be less than 1.25 times the nominal bolt diameter. The value is recommended in Clause 9.5.2 for rolled edges and can be modified in Code setup.
