Simply supported joint between column and beam

[Andrew88]

Hi all,

I want to make a simply supported joint between column and beam for the attached arrangement.

The column is made of a screw pile which comes with the welded plate on top. The beam would be supported by that plate on both ends. I don't want to transfer moment through these joints.

I was thinking about using a set of two bolts on each end of the beam . The bolts then would be designed for shear force and bearing capacity of plates.

The weld between the pile and plate would be designed for the bending moment coming from the bolt force acting on eccentricity against a center of gravity of the weld.

Can someone comment on this, please?

Thanks a lot,
Jed

Both plates on top of piling have to be exactly level and at exactly the same elevation for the beam to sit on top of them correctly. That is expecting much of field work.

I would put a small spacer between the pile plates and the beam with one pair of bolts per pile. Pile plate has to be wide enough to allow space for the bolts.

Thank you very much for the reply and help.

Yes, this will do. I will weld a flat profile in the center of the plate to allow for rotation.

Kind regards,
Jed

If you want to make life easy for the guys building this, and limit the moment to near zero, use a thin elastomeric pad as the spacer between the single pair of bolts.
