Framing & StructuralCâu 298 / 700
For maximum stiffness, how should the long dimension (face grain) of wood structural floor panels normally be oriented relative to the supports?
a.Perpendicular to (across) the joists, with end joints staggered
b.Parallel to the joists
c.At 45 degrees to the joists
d.Direction does not matter for rated panels
Giải thích
Panels are strongest across their length, so the long dimension is laid perpendicular to the joists with end joints staggered so no continuous seam forms. Running the length parallel wastes the strong axis; a 45-degree layout is not a recognized method; and orientation matters even for rated panels.
