Attaching a small column on an existing beam for non-building structure. 1

[Kom3]

Hi,

I am working on a nonbuilding structure and I need to install a new column/post onto an existing beam. The new column/post will be supporting some panels. I have been looking for some design guides but they are all for beam to column instead of column to beam (E.g. AISC design guide 4). Can I use AISC design guide 4 for a column to beam connection (I.e. column sits on top of beam)? If not, are there any references I can use to assist in the design?

Regards.

Kom3,

What is the design code that the local authorities will be enforcing on this project???

HI Jim,

It is the IBC. This will reference the AISC.

What are you looking for a design guide to design? The connection? An understanding of forces and force transfer will allow you to design that connection fairly easily. Doesn't really matter if you call it a beam or a column or a brace.


Are you putting torsion into that horizontal wide flange?

Just design it as a simple point load on the beam... accommodating any moments or eccentricities and check that the beam can accommodate the added loading. Sometimes there are not examples...

Rather than think climate change and the corona virus as science, think of it as the wrath of God. Feel any better?

Are the end reactions for your post primarily axial or shear? Does it need to resist moment too? Design Guide 4 is for shear and moment in the strong axis of the beam (post in your case).

If your post is in compression, then you'll need to make sure that the beam web can support the concentrated loads otherwise you'll need to add stiffeners. Also, depending on what is framing into the beam, your post to beam connection may not be considered a braced point so you may have some stability issues. Any shear or moment in the weak axis direction of the post will require the beam to be checked for torsion.
