I appreciate the feed back, I will get with my boss and discuss some changes that need to be made. Mr. Bob, as far as the siesmic studies, I am in S.E Georgia so that is not something that we really have to worry about. Since you know about sub-stations you will understand what I am referring to, the structure will be placed in the same bay as the regulators and it will have switches directly above, so the weight of the wire will be minimal (there is only going to be 5 foot or so). The brackets on the side of the transformers are the mounting brackets, although not shown, we plan on using those to brace and secure the transformers to the structure.
It was mentioned that there wasn't any description of what the steel was, I apologize for not mentioning, but I had the descriptions listed on the layout page. Also it was asked if the structure is going to be mounted to any thing, yes, there will be a concrete pad poured with bolts installed to secure the structure to the ground. I agree with the fact of the legs being made out of angle is not a good idea, I mentioned that to my boss, prior to drawing, that we should use square tubing and he wanted to go cheap on me!! The transformers are basically 75 kVa distribution transformers, it really doenst have any "feet" so to speak, it's just a round pot with a bunch of oil and copper inside.
Keith, let me make sure that I follow you, you are saying that the two top peices of angle are not adiquate because of the thickness? That if we go with a thicker angle it would be ok? Also if we use something heavier than the 1" x 1/8" cross bracing that it would be ok. We are planning to use 6" channel to run long ways, what if we were to use the same thing on the short side. It was mentioned about the legs buckling
would the channel not help support that?
Like I said in my first post, I am not a structural engineer, and I really appreciate all of the feed back that I have recieved as it will be very helpful in making the modifications that we need.
Thanks again!
