I'd like to build a Vigas roof. Anyone provide any tables to determine the number of Vigas I will need? I'd like to have a 20ft span for them, and hope to use ~8" diameter aged pine vigas beams. For 40lbsf loading on the roof, how close would the vigas beams need to be to each other? 4,3,2 ft?

More helpful would be a way/method to calculate this stuff with varying span distances....
