Bent Steel design
Bent Steel design
(OP)
This is a residential project and I am using Risa 2D to analyze this component.
I have a bent steel beam spanning about 23' and the peak at the middle is about 6' high. I will use steel columns to support the beam. These columns will be inside 2x6 framed wall. Now, how would you analze it? Would you say the base are fixed X and Y? How much load at X direction can I have so that the wall can handle?
OR, shall i say one support is fixed at x y, and the other one is fixed only at Y. How much deflection can I have at the support so it is not too much for the framed wall to take?
I figure the steel columns will mostly take Y direction and I dont want to call it a moment connection. Suggestion? I dont do a lot of steel design in residential. Usually only flat beams.

For analysis you will need to provide horizontal restraint to one point (otherwise the analysis will think its like a car with the handbrake off and will come up with an error).
The lateral deflection at the support is actually your critical design criteria for this one. I would ensure that it is limited to 1/2" at most under typical vertical loads.
Make sure it is well braced to ensure that it is not prone to topple sidewards, and look closely at what happens to the stresses at the bend point.

Now Jike, what happen if one support the wall is 10' long and the other support is 20' long, shall I assume one wall moves more than the other like different spring constants?

yes and yes to your questions.
