Tube-Steel Tower Frame
Tube-Steel Tower Frame
(OP)
I need to analyze the capacity of an existing 60-foot, three-leg, tube-steel communications tower for moment and tension at the base. The 1-1/4-inch diameter legs are 16-1/2 inches on-center and of 50K steel tubing. What are the factors for allowable stress design with regard to tension & bending? This structure was built in 2009. Thanks . . .

Timing has a lot to do with the outcome of a rain dance.

If you are “not particularly familiar with steel design,” maybe you shouldn’t be doing steel design like this. Remember..., practice within your experience level and area of expertise. Sites like this are ‘for help’ but not for a refresher course in steel and steel tower design, assuming you had a first course at some time. There are many basic concepts involved, but it is also kind of a specialized design area and problem, with some of its own codes and design considerations. And, fishing the internet is a darn poor substitute for real answers to these kinds of basic questions. What you really need is a mentor in your office or immediate area, with some experience in steel tower design. Someone who can help you through the various code sections, do some sketches and details with you, actually interacting and talking about the important points of that detail or condition, and watching over your shoulder until you gain some experience on this problem. Ultimately, you better be able to “lay out the entire problem” when you are being asked to “analyze the capacity of a 60-foot, three-leg...” Paddington was suggesting that you consider the problem, and your weak OP, a bit more deeply, so you stay out of trouble, for lack of the full picture.

BTW - good tower design takes some expertise. There is some kind of industry standard for them - I think...and not so cheap software....
