Single angle

[LeonhardEuler]

Can I use a single angle bolted top and bottom for a "small" moment connection? 3.7 kip-in of major axis moment and 1.5 kip-in of torque. The angle would be 4 inches tall and bolted top and bottom

A sketch might help. Thanks!

Are you using it to pick up your handrail and toe plate?

There is nothing really wrong with your concept. You'll just need to check that the connections can take all of the forces, and if that is a plate that the angle is attached to, check it for plate bending. The bottom section or top section might buckle due to compression. Remember, the top rail of a handrail needs to be able to withstand 200#s of force, in any direction.

That being said, 1-1/2" of distance between your bolts, isn't too much distance to pick up your force couple. I can't imagine it would be much tension placed into the bolts, you just need to check them for combined shear and tension.

The handrail is cantilevered out from the angle. So I am getting the ~3.7 kip-in of moment. I am just looking for a sanity check here incase there is anything I am missing besides strength of the bolts/angle such as stiffness of the connection being too low and seeing excess deflection under the 200# load.

Guess it depends on how far you're cantilevering. If it couldn't be picked up by a WT section as in the upper detail, I would go with a combination of the upper detail and the lower detail.
