Problem 8.24
Given
Application floor system Spacing 16 in. OC Load D = 10 psf
L = 75 psfType of panel 16 OC single-layer (combined subfloor-underlayment) Orientation strong direction
Deflection Limits (IBC table 1604.3)
L
(75 psf)D + L
(85 psf)Floor members L/360 L/240
Will a nonveneer panel support these loads? (Load-Span Tables for APA Structural-Use Panels)
APA rated plywood sturd-i-floor
Check a 16 OC with panel in strong direction.
L L/360 270 psf > 75 psf ✓ D + L L/240 405 psf > 85 psf ✓ Bending 1(213) psf > 85 psf ✓ Shear 1(338) psf > 85 psf ✓ A 16 OC span rating or larger oriented in strong direction would work.
APA rated OSB sturd-i-floor
Check a 16 OC with panel in strong direction.
L L/360 245 psf > 185 psf ✓ D + L L/240 368 psf > 200 psf ✓ Bending 1(234) psf > 200 psf ✓ Shear 1(283) psf > 200 psf ✓ A 16 OC span rating or larger oriented in strong direction would work.
∴ Veneer and nonveneer panels can be used.
Field-Gluing Panels to Framing
From APA's Engineered Wood Construction Guide (pages 35-37).
According to APA's Selection, Installation and Preparation of Plywood Underlayment, underlayment should not be glued to the subfloor (page 5).
Nail Popping
Nail popping is when the indentation of nail heads can be seen in thin flooring.
