Framing & StructuralCâu 389 / 700
In high-wind and seismic regions, what is the MAIN purpose of installing metal framing anchors (hurricane or seismic ties) connecting each rafter or truss to the top plate?
a.To speed alignment of the ridge board
b.To provide a ground path for lightning
c.To replace the need for roof sheathing nails
d.To resist uplift and lateral forces that could separate the roof from the walls
Giải thích
Rafter or truss ties create a continuous load path that resists wind uplift and seismic forces trying to pull the roof off the walls. They do not align the ridge, ground lightning, or substitute for sheathing fasteners, all of which serve different structural or safety roles.
