Great thanks. I will check out the Ram products. Another office in our company uses Ramsteel, so they might even have an extra license available.
Thanks very much for the quick replies.
I also found out that AISC has a program which is $330 for members, but it is old DOS based.
I have a couple roof girders which have holes in them at regular spacing for AC duct. I am concerned about beam deflection overall with multiple openings. A single opening does not concern me too much, btu multiple can add up the extra deflection quickly I think.
thanks again.
