Framing & StructuralQuestion 439 of 700
In conventional roof framing, collar ties (or ridge straps) used to resist wind uplift and keep the ridge from separating are generally installed in what part of the attic space?
a.In the lower third, near the top of the exterior walls
b.In the upper third of the attic, near the ridge
c.At the exact mid-height of the rafters only
d.Flat across the bottom of the ceiling joists
Explanation
Collar ties resist ridge separation and uplift and are placed in the upper third of the attic height, connecting opposing rafters near the ridge. Placing them low near the walls describes rafter ties (a different member); mid-height only and flat at the ceiling misstate the required location for collar ties.
