Aust Steel Institute Standard Structural Connections

[sdz]

(I'll try asking again)
ASI in their standard bolted connections use a 65mm web cope with the first bolt 100mm down from the top flange. (This doesn't work for 200UB).

I work in the mining industry and almost all consultants use a 35mm web cope with the forst bolt 70mm down from the top flange.

Does anyone use the ASI detailing? How common is it in other industries?

Persistence pays off.

I would say the 35/70 mm dimensions are more widely used and I can't see the advantage of the ASI standard for typical connections (and I can see some disadvantage in removing more web than necessary).

I expect they just used a number which allowed for the thickest flanges.

I would exepect that the smaller cope would be beneficial if anything.

I detailed a 360UB today that used the 35mm web cope. In my company, the 35mm cope is the standard design.

You are right with the 200UB, if you provide the 65mm cope then you will only be able to use 1 bolt if you use a 35mm min edge distance, so I would definately use the 35mm cope.

Hopefully the revised connections manual will account for this.
