HSS Column Selection for 4 Story Structural Steel Building
HSS Column Selection for 4 Story Structural Steel Building
(OP)
I've been tasked with designing columns for a 4 story building (interior columns only, the perimeter is concrete tilt wall).
Story Height: 15 feet
Floor: Vulcraft VLI composite slab/metal deck with open web steel joists and wide flange steel beams.
Roof: Metal Deck
Column Shape: Square HSS
Approximate 250 feet x 140 feet and 27 feet bays.
Column loads (unfactored/unreduced) up to 600 kips.
Question: In general, what do I need to keep in mind when selecting the sizes and specifying changes in sizes?
What's easiest to build?
Pointers in general?
What are good references? I looked on Google and sifted through the AISC design guides with no luck.
Thanks.

Quick research showed columns should be no more than 3 stories, so if splices are expensive it may be good to go with one splice only, at 3rd floor. ?Makes it about a 32 foot column which I imagine can be easily transported.

I would think there are several design guides from AISC that might be somewhat beneficial; 5, 7 (maybe), 22, 23 and 24.

PU, I agree if there is a requirement from the owner or architect that tubes should be used, but if a tube is being used strictly because it weighs less then that economy may be untrue due to other factors.

SteelPE- I took from the attached post that the Kirk, upon researching more, found the column should only be 3 stories tall, 3x15= ~45'. Perhaps I'm misreading. If column is 60', yes I would splice.
