Framing & StructuralCâu 343 / 700
In a wood-framed building, what is the PRIMARY role of a floor or roof diaphragm in the lateral system?
a.To collect lateral (wind/seismic) forces and transfer them horizontally to the shear walls
b.To carry only gravity floor loads
c.To provide the finished floor surface
d.To insulate the floor cavity
Giải thích
A diaphragm is the horizontal sheathed floor or roof plane that collects wind and seismic forces and distributes them to the vertical shear walls that carry them to the foundation. Gravity load, finish surface, and insulation are separate functions, not the diaphragm's lateral role.
