Bent Clip Plates

[Subject Prev][Subject Next][Thread Prev][Thread Next]
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
plates. 

My question is are these type of cracks typical for bent plates?


Thanks In Advance!
