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 floor system is 24-in. o.c. Floor dead load = 18 psf. Floor live load = 125 psf. Floor sheathing is to be an APA rated OSB sheathing, and panels are to be oriented in the strong direction. The load is governed by bending and shear 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 40/20 be adequate?
