how to design a beam with handrail attached to top ?
(OP)
Hi there,
I am working on a beam with handrail on top of it, I think I may need to consider torsion, but how much I shall consider? Any other issue I should pay attention to?
Thanks.

The floor diaphragm could take one component of the torsional force and the transverse floor joists or intermediate blocking the other.

An approximate conservative method is to convert the torsion into a couple the depth of the section and apply the resulting horizontal loads to create weak axis bending. Check the moment over half of Sy.
And don't forget that the torsional load needs to go out through the connection(s).

The greatest trick that bond stress ever pulled was convincing the world it didn't exist.
