Framing & StructuralQuestion 318 of 700
In conventional roof framing, where should rafter ties (which resist the outward thrust of rafters) generally be located?
a.At the ridge
b.Halfway up the rafter length
c.In the lower third of the attic (rafter) height, near the top-plate level
d.Anywhere, as long as they are nailed to the rafters
Explanation
Rafter ties resist the outward spreading thrust rafters exert on the walls and are most effective near the bottom of the rafters, in the lower third of the attic height. Placing them at the ridge (collar-tie zone) or midheight greatly reduces their ability to hold the walls in; location is not arbitrary.
