![]() ![]() Collar ties I don’t believe do anything to resist outward force at the walls. ![]() I will use straps instead of collar ties. I think the formation of the triangle as a result of the rafter tie really stiffens up the roof, ie ridge in addition to supporting the walls from bowing. Do I need to actually tie the rafters together? Or is a wall that is tied by joists 12†below the top plate sufficient? I think it is.sufficient but it does have me thinking about it. if not, then a “TRUE†rafter tie will span the distance in the lower 1/3 of the rafter. If there is a gangway- a tie will be made through the gangway. Therefore there is a 10’ section with no ties at all. ![]() The lofts may or may not be joined by a small gangway. Yes- the joists are outside of the rafter triangle, but I THINK they are close enough (12†only) where they will still do the job of resisting outward force of the rafters. and the joists for the loft will span the entire width of the cabin- thereby tying the walls together. My lofts have kneewalls that are part of a continuous wall from the floor where 12†only will protrude above the floor of the loft- effectively creating a knee wall. Code is not required in MN where I am building. and the only real problem I am potentially worried about is the lack of rafter ties. I am building a cabin that I designed - 22’ wide x 28.
