Framing & StructuralCâu 303 / 700
Which panel-joint practice BEST avoids a continuous weak line across a subfloor or roof deck?
a.Aligning all end joints on the same joist
b.Gluing every joint solid so panels cannot move
c.Using only full sheets with no cut pieces
d.Staggering panel end joints so they fall on different supports in adjacent rows
Giải thích
Staggering end joints (a brick-like pattern) keeps adjacent rows from sharing one continuous seam, distributing load and stiffness. Aligning all joints creates a hinge line; gluing does not address the seam pattern; and using only full sheets is neither practical nor the governing principle.
