Stainless steel beam design

Stainless steel beam design

Stainless steel beam design

(OP)
Has anyone designed a simply supported beam with stainless steel, Allowble Stress Design method for with the US product?
I am looking for a simple example calculation?
I appreciate if anyone has a short sample of work so I get my feet wet

I am not following the AISC Design Guide and please dont refere that.
Thanks

RE: Stainless steel beam design

I am confused as to why you don't want to use the AISC design guide. That has great examples to get your feet wet. All you would have to do is change material properties.

I am not fsamiliar with the new ASD notations
Safety factor Omega ,....

Did not see where telling me what is Fb clearly to use as we used to use 0.6Fy or 0.66Fy

I need a simple example in simple language

And where do I find cross sections and section properties??? Whereas in the green book is in the book?

Is E modulous of Elasticity the same as for Carbon steel?

I appreciate any help

RE: Stainless steel beam design

I understand.
If you go to http://www.aisc.org/content.aspx?id=2868 you can download an excel file with all the steel shape information as far as cross section goes. As far as the elastic modulus goes with all steel there is a range however the standard value can be applied to SS as well. If you can confirm that the cross section of the shape is compact then you don't have to worry about any local deformation and can just use Fy*Zx for the moment capacity. The omega is just the safety factor.

Are you telling me the section properties of for example W 12 x 26 with carbon steel (where is in the 9th edition) is same as W12 x 26 Stainless Steel?
is now "Z" is the new way of showing elastic section modulus "S" ?

RE: Stainless steel beam design

Yes the geometric properties of it remains the same. The Z is the plastic section modulus. It's the current standard now in place of the section modulus. It allows for a more efficient beam design.

"Yes the geometric properties of it remains the same. The Z is the plastic section modulus. It's the current standard now in place of the section modulus. It allows for a more efficient beam design."

Can you elaborate on this?

RE: Stainless steel beam design

Z should only be used if the section can reach full yield. I don't believe stainless steel provides the same ability as standard carbon steel. I would be using the elastic section modulus S.

RE: Stainless steel beam design

What type of loads are being applied? What is the application of this beam? It might be better to use a galvie beam instead of SS.

Depending on the loads applied you need to check lateral tortional buckling, flange local buckling, web crippling, shear etc.

Thank you all for your assistance.

RE: Stainless steel beam design

Did my post get deleted? I had posted an example...

RE: Stainless steel beam design

SKJ25POL - Our colleagues may have missed that you want to perform the calculations using obsolete Allowable Stress Design. I can show you how this can be done, using the AISC 9th Edition (green book) as a guide, if you want to see it.

No elaboration necessary on this.
