There are recommended minimum bend radii for bent plates in the AISC Manual that are intended to eliminate cracking problems that do occur when plates are bent to too tight a radius. See page 9-129 in LRFD 2nd Edition or page 4-174 in ASD 9th Edition. Same table either way.

Subject: Bent Clip Plates
A contractor has requested(at the behest of the site inspector) that I
inspect bent clip plates(used to transmit beam gravity loads) due to the
presence of cracks at the outside corner(they radiate from the N.A. to the
outside corner) of the bend. The cracks(two) also occur at the top and
bottom edges of the bent corner of the plate. They are almost "surface"
cracks in nature in that they are approximately 0.03 in wide and 1/8" deep.
The plate is 5/16" thick and 5 1/2" wide. The one outstanding leg is
oriented approximately 120 degrees relative to the other. I've requested
what bending radius was used and if the plate was bent parallel or
perpendicular to its "roll".
Since the transmitted reactions are "light"(less than 4 kips), my
recommendation is to surface grind to remove the cracks and install the
My question is are these type of cracks typical for bent plates?
Thanks In Advance!
