plazma cut holes @ conn. plates?
(OP)
Sirs,
What a great website!
My question is regarding AISC specs on holes designed for connection plates using HS bolts. Is it primarily a dimensional requirement? If so, what about the slight taper created by in the kerf of the cut? We are interested in burning these plates vs. layout/punching due to the ease of manufacture.
Thank you in advance,
Jeff

I would be very cautious about using flame-cut holes in bridgeworks, because the rough, hard profile of the flame-cut surface would be susceptable to fatigue.
Also, before you commit to flame-cut or plasma-cut holes, check the economics. It probably takes more time and energy to produce the initial pierce than to cut the profile of a small hole. I know with flame-cutting, the direct cost per pierce is about $1, which is about the same as the cost of drilling through 20mm plate.

Q---I am surprised that , considering your background with JFB that you wouldn't be " totally anti flame cut holes"! I have 'chopped' a few in my time, but I doubt it would be legal today.

In the shop its a different story, especially for very thick plates that can't be easily punched. In the shop at least there are more eyes looking over the workers - or so I've been told
