Use APA Technicаl Nоte Q225 entitled Lоаd-Spаn Tables fоr APA Structural-Use Panels and ASD procedures to answer the following question.The spacing of joists in a flat roof is 32-in. o.c. Roof dead load = 14 psf. Snow load = 55 psf. Roof sheathing is to be an APA rated plywood sheathing, and panels are to be oriented in the strong direction. The load is governed by deflection limits of L/240 for snow load and L/180 for total load. Only consider these limits. Assume multi-span, normal duration of load, dry conditions, and panels 24 inches or wider. Would a panel with a span rating of 32/16 be adequate?
