I'm curious why you are going so narrow (14')  ???

I would expect I would feel real confined in such a narrow and long building. But figure you have a plan, or a restriction that makes sense.

Will post a pic of my layout. Everything should flow from one end to the other. Just need it wide enough to work in as narrower is cheaper and longer is easier to layout without tripping over things ;)

I have a unique situation that Im having trouble working out. I am making a bent with about an 8/12 pitch that spans 30. Im using red and white oak. It will not have a roof. Its for an entrance to a ranch. It will have two top chords, a king post, two struts, and a bottom beam. Heres what Im thinking so if anyone has any comments Id greatly appreciate them.

The materials are red and white oak. 

2 posts. 10x10x8 
2 knee braces. 10x10x6
1 top plate. 10x14x32
1 king post. 10x10x8
2 top chords. 10x10x17
2 struts. 10x10x6

My concern is whether a 14 beam can carry the load without sagging. Theres no roof or snow load. Its just a bent at the entrance to a ranch. Please if you have nasty comments just dont bother responding. Constructive comments are greatly appreciated.

I forgot to mention that the 10x14x30 beam will not be scarfed. It will be milled to length.

I can understand that this is an entrance to a ranch, but 8' post seem kind of short.
Will they be up on some concrete piers to get the clearance under the bottom chord of the truss?

If you need to get a moving truck or semi in min 13'6" go 14 or 16 ft clear.

You won't be wrong using 60 lbs per CUBIC foot (12 BF) for green oak.
Then plug it in here;

That is checking the wood strength, the joinery is the next kettle of fish.

A metal cap formed for the top will help it last longer. And of course the more white the better. I borate and then put a water repellant finish on porch posts and such.
