Detailing of bolts and welds according to Hong Kong Code
Bolt minimum spacing is according to Cl. 184.108.40.206: Centre to centre of bolt should be larger than \(2.5 \cdot d\), where \(d\) is nominal bolt diameter.
Minimum edge distance measured from the centreline of the bolt is according to Table 9.3:
|Bolt size||Minimum edge distance [mm]|
|M24 and over||\(1.25 \cdot d\)|
Minimum leg size of fillet welds is checked according to Table 9.1.
|Thickness of the thickest part [mm]||Minimum leg length [mm]||Minimum throat thickness [mm]|
|\(t \le 6\)||3||2.121|
|\(6 < t \le 13\)||5||3.536|
|\(13 < t \le 19\)||6||4.243|
|\(19 > t \)||8||5.657|
