end-plate connection with slot holes to transfer axial load only 2

[TTTKAO]

Hello Everyone,

I am designing a stabilizer which will provide lateral support only for a structure.

the stabilizer is a W shape beam and connects to column flange directly. I plan to use an end-plat connection between
beam and column. and set vertical short slot at column flange and horizontal short slot at end plate to release shear load at this connection.

May I ask is there any concern for this connection to transfer axial load, I am wondering if the slot can transfer axial load properly?

Thank you for your advice and suggestion in advance.

So you don't want shear load transferred? Well then you now have a cantilever and need to design that beam as such.

You are also almost asking the impossible. To transfer axial loads you need contact, and with contact comes friction and with friction come shear transfer.

If you are wanting to transfer compressive axial loads only then you can start getting close, if you really tried hard and allowed for self weight deflection. This connection could start looking like a slip bearing connection used on bridges or other expansion joints.

I wouldn’t be concerned about the axial load, it will function that way, however like hokie said, the slotted holes will also transmit some shear.

Slotted holes are essentially fuses. At a certain point they slip, but not initially. Sometimes it never happens. The shear loads can be quite high before it happens.

Hi Tomfh and human909 ,

Thank you for the opinion and suggestion.

The beam(stabilizer) connection to column in one end and connection to drift wall in the other end which i didn't show it on sketch, sorry for the confusing.

the shear load is not big , it's ok to take some shear load for this connection as long as it can transfer axial load well.
