Angle Design for Fixed End?

[mfleming]

I'm looking to design a steel angle that can support 50lbs uniformly distributed. It will be fixed at one end and the length would be 1'-6".

1'-6"
-/------------/-

This should be pretty easy but I can't remember how to calculate steel angle or even what to design for ie. Ix,Sx ect.

Can anyone help me out.

Thanks

Matt

The new 13th Edition Steel manual deals with this in Spec section F10. The 9th Edition ASD Manual deals with this on page 5-311. These are not overly easy checks, but this will tell you what to do.
I hope this helps.

I don't have either of those. All I have is "Handbook of Steel Construction" Seventh Edition (Canadian)

alright, let me know if you want the 9th edition version or the 13th edition version and I will attempt to post it.

 

[mfleming]

Either one should be fine. Pick the one that is easier to understand.


Thanks

This will be much easier. Visit this website, it is the spec for the 13th edition. Look at page 16.1-57, this is where the single angles in flexure starts. You will probably have to copy and paste it into your address box.

You need to have the proper codes for your area. If you're the AISC 360-05 is adopted in yoru area, you can use the link provided above. If not, you just need to go buy it. No one shows up on site with no tools and expects to borrow them for free, engineers shouldn't do so either.

Angle properties can be calculated using mechanics of materials, just like in school. You can find properties for angles in many texts I expect and in the AISC manual as well.

If your angle is made of cold-formed steel, then you need to be using the NASPEC for cfs. This code is adopted in Canada, the US and Mexico.

This seems like an overly simple question. Given that you don't know how to do this and have no materials either, are you an engineer qualified to do this calculation?

I have the proper codes for my area. "Handbook of Steel Construction" Seventh Edition from the Canadian Institute of Steel Construction. Thats not the problem.

This is an easy question... well I thought it should be. I mainly to beam & column design and haven't done angle design for some time now and I forget.

I thought someone hear could give me a quick solution for a simple question.

I guess I'll have to get into my storage and find my books on it.

Thanks

mfleming-
Design of a single angle for flexure is not as simple as designing a regular beam. It is much more involved, and AISC gives different criteria depending on a number of factors. It is not as straightfoward as giving you one design process.

I'm switching to a small HSS tube. So much easier.

Thank you,

Matt
