Hefty columns
(OP)
Hello everyone!
I just want to find out your opinion about hefty columns in high-rise buildings or heavy-loaded structures: which type of column section is more economic - box column or jumbo section + cover plates? Any other pros and cons for each type of section?

RE: Hefty columns
In the literature that I've read, cruciform sections formed from a Wide flange and two WT's seem to get mentioned a lot. An advantage with that system is that you've got an accessible flange to bolt clip angles to on all four sides for girder connections. It seems to me that a cruciform cross section would have a relatively lousy torsional buckling resistance but that doesn't seem to be holding anybody back.
I can't wait to hear everyone else's answers!
The greatest trick that bond stress ever pulled was convincing the world it didn't exist.

Since the boiler and its structural steel are usually purchased by competitive bidding, economy is a major factor.
