Monorail support

[gg79]

Hi!

I'm designing a monorail which is support at three points. The monorail beam (I-beam) is bolted in its upper flange as shown in the enclosed sketch. Since it is a continuous beam there will be a bending moment over the middle support. My question is: Do I have to design the bolts for this bending moment or only for the vertical load? Is it depending on the rotational stiffness between the supports vs. the monorail beam?

Design the beam for the moment and the bolts for the reactions. But no moments in the bolts. It's a continuous beam over simple supports.
