The structure is symmetrical and the beam is continuous. (it actually represents a shaft freely rotating inside 3 plates, which are the 3 "supports")
The black dot at B is just there to show that I'm approximating B as a pinned support (just as a formality so that the system isn't technically...

A and C are known to be equal however, so there are really only 2 unknowns.
A, B, and C are known to all be pointing downward.
At first glance this looks like a pretty easy/standard statics problem. But...
Sounds like many/most people who are using it, are using it mainly for wood design. I've actually never used it for wood. I use it daily for steel and steel only (onshore drilling structures).
(Firstly, hi! I've been lurking on here for a while, and this is my first ever post.)
We use SAFI for structural analysis at my company. (Specifically, we use it with the AISC Spec, mainly the 2016 and 1989 Editions)
I've noticed that it does not seem to be very widely used; searching Google...
