Ask Structural Engineering Questions and Get Expert Answers ASAP
Can you explain your structure in a bit more detail? Not sure what a "10,000 unit" is.
Can you provide a link to any kind of picture of a similar structure on the internet?
Let me know when you come back online
Thanks for the drawing and information.
So just to make sure, you want to temporarily lift this AC unit with two Steel Channels and move it over to set it into it's permanent location, correct?
One more question, the AC unit will rest on it's 4 corners only, correct?
Before we get started I’d like to point out that a Professional Engineer’s standard of care typically includes a site visit to assess field conditions and get an overall understanding of the structure. This can obviously not be accomplished through the internet. The information provided here is meant for planning purposes only (general sizing and budgeting) and is based on the information provided by you. All loading cases considered are for vertical loads only, no lateral analysis has been completed. The information should be verified by a professional engineer who can visit the site to ensure that potentially important information has not been overlooked or omitted.
Since we do not know how the unit will rest on the steel members, I will have to be conservative and assume that half the unit load will be placed at the midspan of each member.
Your proposed channels are too small.
I would suggest using structural steel tubing or small W section steel beams. You could use:
two T 6x5x 1/2" (50 ksi) structural steel tubes
two W8x15 (50 ksi) steel beams
I am concerned with possible lateral buckling of your proposed C channels when the AC unit is lifted and moved.
Let me know if you have any questions.
