Rafter size
Hello,
I'm building a picnic pavilion and was trying to figure out what size rafters I need. I'm trying to get away with 2X4's 24" OTC. The building is 10'X16' so the span is 5' on each side. There will be an overhang of about 2 feet. So the rafter needs to be 7 feet but for calculations it is only 5 feet (ridge board to top sill plate). Can I get away with 2X4's? I'm in southwestern PA, zone 5. Here's the stats for my area: Code: BOCA 1999 Wind: 80 Ground Snow: 25 Live Load:20 *Roof Snow:18 Exposu B Acceleration Coefficient (Aa):0.05 *Roof Snow is a calculation based on the Ground Snow. Thanks, Sam Hopkins |
