Steel Deck Diaphragms

[Subject Prev][Subject Next][Thread Prev][Thread Next]
I have specified a 22ga. steel deck  with puddle
welds at supports and #10 TEK screws at side laps.
The field has "supplied" a punched (button?) hole
at the side laps. My questions are:

1.    Is this crimped button hole comparable to
the TEK screws for side lap shear transfer?
2.    If so, is there available information
regarding substitution?
3.    Is this method (punched hole) considered a
stitch fastener?

Comments appreciated.
