You say the load is 30 feet long, supported every two feet. So, if the
load is uniform, it will be supported in 15 or 16 places. If we assume
15 places then each arch of the building will need to support 86.67
pounds. My steel arch building, which I think is similar to yours, is
rated for 70 pounds per square foot snow load. However, your building
is twice as wide as mine and two feet taller. What is you building
rated for? Do you get that much snow? Since I never get more than 8
inches of wet snow I would not hesitate to put that type of load on my
building if I needed to.

I made a correction in another post , but my real load is 600# in 30' or
1200# in 60'.
What I really need to know is how much load will a 2"x6"x1/8" wall tubing
carry in an arch of 60' wide by 20' high at the center of the arch.
