seat angle connection
seat angle connection
(OP)
I have a connection that employs a seat angle supported on two gussets; one gusset on either end such that the angle is simply supported.
A hanger rod is bolted through the seat angle in the center of the span.
What is a good approach to checking local bending in the seat angle?
I used an approach I have used before for checking local flange bending in underhung monorails, but if I employ this method, the bending stress in the angle leg is very high. The method I am using is a more or less a yield line approach using a 45º yield line back to the "k" distance on the angle in order to get a bending width for calculating the section modulus.

We axis bending of the angle leg, but what is the tributary length? Yield line can be time consuming. Local stiffening may be quicker (i.e. cheaper)

It is an existing connection.
The hanger rod is 4" from the heal.
I am wondering what is the best way to check this design. From doing a quick yield line the stress is very high.
Also, I cannot really just analyze this as a simply supported beam as the 4" eccentricity from the shear center will cause torsion, no?
The angle will not bend about the geometric axis.
