Steel Beam to Concrete Wall With Bearing Plate Connection 1

[FabioBorini]

Hello all

Could someone give me an example or guidance of how to connect a steel beam to concrete wall??

thanks

Is the beam supported by concrete walls on both ends? Is it framing into the side of the wall or bearing on top? Use embed plates and simple shear connections for framing into the side of the wall. If it is a bearing type connection, use embed plates at the top of the wall and weld the bottom flange to the embed plates. Typically when I use bearing plates, I make sure one end has a slip connection.

Steel beam on top of the wall or into the side? Parallel to the wall or perpendicular to it? Wall poured already or to be cast in the future? In my experience, the most common connection is:

1) An embedded plate cast into the wall.
2) A shear tab or angles welded to the embed plate.
3) A bolted connection between the shear plate / angles.
4) Short slotted bolt holes to provide erection tolerance.

I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.

We must have been typing at the same time Mike. Glad to see that great minds think alike.

how to design or what are the limit States design of this connection?

 

[KootK]

1) Bearing stress on grout and concrete.
2) Flexural capacity of bearing plate if you have one.
3) Web crippling and yielding and need for beam stiffeners.
4) Bolt and anchorage design if connection resists tension or shear.

That's a good start.
