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 60-in. o.c. Floor dead load = 14 psf. Floor live load = 136 psf. Floor sheathing is to be an APA rated OSB Sturd-I-Floor sheathing, and panels are to be oriented in the strong direction. The load is governed by a deflection limit of L/240, 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 24 oc be adequate?
