Framing & StructuralCâu 365 / 700
On a raised residential deck, guards are required, and the guard infill (balusters/pattern) must be designed so that which object cannot pass through?
a.A 6-inch sphere
b.A basketball
c.A 5-inch sphere
d.A 4-inch sphere
Giải thích
Deck and balcony guard openings must be small enough that a 4-inch-diameter sphere cannot pass through the infill, protecting small children. A 6-inch or 5-inch sphere limit is too loose for guard infill (6 inches applies only to the triangle at open stairs), and 'a basketball' is not a code criterion.
