Does anyone know why you need trusses? If you look at old barns that are surely around 150 years old, it's perfectly fine with two logs of 15 cm diameter set in an upside-down V shape. These have been standing for a while and during that time there have surely been winters with a lot of snow. Moreover, the V's are usually spaced quite far apart. Can similar constructions be made now that are approved?

If you look more closely, you'll see that it isn't as simply constructed as you describe it, they often have a ridge beam, similar to a vaulted roof.
You must have simply seen it wrong.
If the construction were as you describe, the walls would be pushed apart by the "logs" when pressed down and out by the weight of the roof, with or without snow.
Look a little closer, and you'll surely see some horizontal "logs" too, going from wall to wall, holding the construction together.
You know, the ones the barn swallows' young usually sit on.
Together, your logs and mine form rafters.

Well, it's not always that there are horizontal logs either. In my old man's barn, for example, there aren't any because then the wires for the elevator would get tangled quite often 
. But I guess it's somehow compensated by how the roof truss is attached to the wall plate and how the wall plate is fastened and the strength of the log floor.

Well... I probably don't understand how it looks if there aren't reinforcements to keep the walls in place....
