There is a
W6x8.5. I don't how likely you will be to use it, though.
I know that some of you are going to read this
and say "Wake up Ken, these have been out there for a while now", but just in
case some of you don't know this, I feel obligated to share this:
I am looking at a job to bid and I see W21x55
beams and I say to myself - "must be a W24x55 or W21x50". Just in case,
I check the LRFD 3rd edition and sure enough there are two beam sizes in there
that I was not aware of - W21x48 and W21x55. I knew that the big W44's
were vastly different from the 9th edition, but I had not realized the changes
to beams in the range that I use fairly often. I will have to
pencil these into my 9th edition! Without me going through the entire
list, are there any other new lighter (say less than 100 plf) wide flange
members that I should know about?
