Salt can you explain to me what you are trying to do.
I thought you were going to build a tunnel.
As for Drew's picture all he would of had to do is run a pole across the top.
I put steel rods in the ground and set a trellis on them.
It was 10 feet long and ten feet tall.
All of it was made out of 3/4 ridged conduit.
At the corners at the top I used 90 degree pipe elbows.
I made two of them and set then about four feet apart and grew cucumbers on them.
You dont have to make heavy duty stuff you just need to construct it properly.
Do you have a cheap drafting compass and squares at home like they used to have us buy in school.
With this you can design many things on paper before you build it.
I have a set and I use them a lot for many things before I make them.
One time I figured out and make a wrap around that you use to cut out notches in tubing for race car crash cages.
Here are some common terms you can use that will help you.

These two alone will allow you to come up with things that are structurally sound for the application you will be using them for.
Even the re-bar can be used if supported properly with bracing and wire.
Here is a simple way to make a Gothic arch showing how make the radius you need to make an arch of a certain height and width.
All you do is draw circles and cut them in half.
