AS3600 - Cogs & Hooks
(OP)
I understand code provisions for standard cogs on end of reinf bars. What about if you have a non standard cog with the tail either greater or less than a standard cog? Can you adjust the anchorage provided in some way to allow for this? Especially, if you have a tail equal to the development length can you count it as full anchorage or are you still restricted to the cog providing 1/2 of the required developmentlength?
Same for hooks.
Same for hooks.

I would be cautious about having a hook/cog length less than the standard lengths nominated in AS 3600.
RE: AS3600 - Cogs & Hooks
I wouldn't use greater than 50% of capacity unless you have calculated that concrete crushing and/or splitting will not occur.
If the length is less than standard I would use that length as if it was straight bar.

You may be correct, I haven't had cause to use that clause before.
RE: AS3600 - Cogs & Hooks
I understand this as meaning that you aren't limited by the 50% rule, the entire development length can be within the curve and beyond.
