Eccentric Horizontal Bracing to Beam with shear connection

[N G P]

I have a doubt (which is very elementary) on a connection type for an eccentrically connected horizontal bracing to a beam.
As shown in the below figure, the horizontal bracing is connected to the beam-column joint with an eccentricity of about a dimension equal to the depth of the beam (say 400mm). The beam is connected to the column web by an extended vertical fin plate. This is as suggested by the client.

The structural model is developed and provided by the client which neglected the eccentricity and the bracing is connected directly to the column beam joint.
Since the bracing has a significant tension and compression force, as I can imagine, the bracing force will develop a horizontal (transverse direction) shear and bending moment in the connection.
The fin plate connection is not capable of taking these loads. But I have come across different external drawings with similar types of connections.
My question is whether it is necessary to consider the bending moment due to this eccentricity and what could be the ideal solution or type of connection for this particular situation.

I too see this type of detail often. It isn't something I would tolerate.

I am just planning to provide two horizontal fin plates to connect with the top and bottom flanges of the beam to be able to carry the transverse shear from the bracing forces (as shown in the figure). The bracing forces are applied to the joint as horizontal and axial force components based on the angle. I have ignored the eccentric moment on the connection by assuming the beam will bear at the connection as pinned itself.

Do you find this a reasonable assumption and the connection a workable one?

You can definitely control the load path w/ fin plates, as you have shown in your connection concept model, but the proper connection to take the additional eccentric forces will vary depending on member sizes and brace load magnitude.
