Overhang on the support beam

[Derbyboy]

Does the overhang outside the post affect the deflection inside the post?

In Träguiden's program, you can calculate a storage building with overhang/eaves for the roof beams, but it is not possible to assume that the support beam will extend beyond the outer posts.

Yes, it reduces the sagging. If you calculate without overhang it becomes conservative.

?

I rephrase myself.

Yes, it reduces the deflection if you have an overhang outside the support beam. If you calculate without an overhang, the result will show greater deflection than in reality.

Ah ok thanks, that was indeed positive.

But it increases the strength on the post, right? Just so I'm keeping up.

Then there's surely some rule about how far overhang you can have depending on the dimension and length of the support beam.

Which pole?

The outer….

Yes, it gets the entire load from the overhang and some more from the load inside.
