RE: Curved Steel Beams

[Subject Prev][Subject Next][Thread Prev][Thread Next]
I kept an edition of the AISC Journal that addresses this very issue (March
1993).  They recommend a minimum radius of not less than 10 to 14 times the
depth for the strong axis.  Might be worth a call to a fabricator/roller to
confirm.
12 feet sounds too small for a W16.
