lateral deflection portal frame
(OP)
Can someone give me a formula to calculate (or estimate) the lateral deflection in a fixed base portal frame. I col and I beam are the same. Thanks for your help.

But you can also try "Rigid Frame Formulas" by Kleinlogel - one of the classics. You probably want frame #41.

You can arrive at the same result using Kleinlogel but it will take several pages of computation as Kleinlogel does not directly provide the equations for drift/deflection.

rittz are you designing by hand ? or using software ?

Designing by hand and excel .. that's it

If you're worried about deflection, they're service level loads anyways. So your structure will most likely see these loads.

Thanks for the tip. It looks ok for my application

Not that I design portal frames by hand but still very good.

You were right about Kleinlogle - no deflection formulas, and the same applies to the book by Seelye ("Data Book For Civil Engineers - Design", 1964 by John Wiley & Sons). Sorry for that.
That being said, they are still excellent references to obtain for your library.
