Framing & StructuralCâu 347 / 700
What is the main purpose of a hold-down (tie-down) anchor at the end post of a narrow shear wall?
a.To resist the uplift/overturning tension generated at the wall end and anchor it to the foundation
b.To level the top plate
c.To provide gravity bearing for the roof
d.To seal the wall against air leaks
Giải thích
A hold-down connects the end post (chord) of a shear wall to the foundation and resists the tension uplift that lateral load creates as the wall tries to overturn, which is critical on narrow walls with high overturning. Leveling, gravity bearing, and air sealing are not the hold-down's function.
