steel tube frame
(OP)
Hello, I am needing some help on ensuring a steel tube frame can withstand compression, moment, deflection, vibration effects.
I am attaching a pdf drawing of what we have in mind: we are assembling a steel tube frame with s.s. plate which will be welded onto the structure, and will hold power panels, monitors, transformer and control panel via screws.
Materials of construction consists of 2x2(1/8) ss tube with a ss 1/8" plate, main form of connection is welding.
Main concern is insufficient bracing for lateral motions.
Input is greatly appreciated.
Individual weights of equipment carried by the structure:
480V power panel(60#),
240/120V power panel(40#),
5kVA step down transformer (90#),
ambient monitor (5#),
phase monitor (5#),
control panel (100#)
Square steel tubes - 3.05#/ft

1) Overall frame action for wind will probably govern.
2) Check local stresses at connections since it is only 1/8".
3) It would seem to me that additional ss tubes in the proper framing configuration would be cheaper than a large plate. But that is your estimator's call.
4) A thin plate may not be able to handle the drum load from wind combined with the load from solar panel. Check the load combinations for that, especially if it is only 1/8" flat plate.
