Can you take a look at the following link and answer the questions at the bottom of the sheet? Your answers will allow me to accurately model the loading and size your beam. Thanks
Just want to make sure I am sizing the correct beam. In your first post, you said this beam will support 1 floor and roof. Then you say New Joist Span #3 from my sketch, which supports ceilin and roof. Can you look over your project and let me know which beam is correct for your situation.
Let me know when you come back online
