![]() How did you all figure this out? Are there tools out there to calculate this? "a ridge beam needs to be sized based on loads, distances etc as well as be designed to bear the weight down to the foundation. My main point was to clarify board vs beam. With a 8x12 your really not going to have much of a loft because the building is so skinny.Īgree. ![]() I used LVL build up beam for my 16x24 allowing for an open space and lots of loft headroom. Not to mention the need to be very attentive to the span tables etc. Disadvantage is can be harder to get up, impacts design and generally more cost. Rafters can then be hung off the beams which substantially reduces the size (ignoring need for insulation space) and generally removes the need for collar ties. a ridge beam needs to be sized based on loads, distances etc as well as be designed to bear the weight down to the foundation. That is a ridge board that has no structural use just makes it easier to put up the rafters and you still need collar ties etc. ![]() Im no engineer.and agree that a 6/12 pitch would be nice to work on, but in a snowy area I think you may need more?Ĭlarification - 2x8 is not a ridge beam. I'm in New England so there will be snow. Say I use 2圆 rafters, a 2x8 ridge beam, would I still need collar ties? If so, do I need them on every rafter? Do I need rafter ties? If so, do I need them on every rafter or can I do every other one? What size rafter tie? 16 or 24 oc? I'd like a vaulted ceiling, and I don't mind exposed beams/joists, but preferably not every 16". I'm having a hard time finding a good design. I don't like trusses, so I'm looking to frame my roof using rafters. ![]() Small Cabin Forum / Cabin Construction / 8x12 rafters sizing/roof frame designĭoes anyone know of any 8x12 roof framing plans that have been verified by an engineer?
