Hello, my question is...

Hello, my question is for a 32’ span, with 12 foot rafters and a 4/12 pitch with comp roof what would be the recommended steel I-beam?

Tutor's Assistant: OK. Tell me a bit more about what's going on so we can help you best.

Thanks Pearl, so this is for a ridge beam.What else do you need to know?

Tutor's Assistant: Is there anything else the Structural Engineer should be aware of?

Just old Skip sheeting and Half-inch ply over that. The rafters will be doubled up with 2 x 4 spending the entire rafter distance and a 2 x 6 run in the entire rafter distance every 24 inches.

Would it make any difference if the 12' rafters are two ft. of rafter tail each?
Is it 12 feet plus a 2 foot tail? Or 10 feet plus a 2 foot tail
