The following load-span tables apply to APA trademarked structural-use panels qualified and manufactured in accor dance with APA PRP-108, Performance Standards and Qualification Policy for Structural-Use Panels, Form E445, Voluntary Product Standard PS 2-04, Performance Standard for Wood-Based Structural-Use Panels, Form S350 and Voluntary Prod...
APA Rated Sheathing panels are produced as plywood or oriented strand board (OSB). Typical size is 4 ft x 8 ft, but other sizes may also be produced. Commonly square edge, but may be produced with tongue and groove edges. 2.4 Common Performance Categories And Corresponding Span Ratings Performance Category Span Rating 3/8 24/0 7/16 24/16
structural panels include structural plywood, oriented strand board (OSB), other mat-formed panels, and composite panels. The standard classifies panels by bond classification, span rating, performance category, and grade.
For each combination of span and thickness (or Span Rating), loads are given for deflections of L/360, L/240 and L/180, and maximum loads controlled by bend-ing and shear capacity. Uniform loads for some applications can be read directly from the tables.
There are three possible span conditions to consider when computing the uniform load capacities of structural-use panels depending on the size and orientation of the panel and the spacing of the framing support members.
SPAN RATINGS. APA RATED SHEATHING, APA RATED STURD-I-FLOOR and APA RATED SIDING carry numbers in their trademarks called Span Ratings. These denote the maximum recommended center-to-center spacing in inches of supports over which the panels should be placed in construction applications.
APA Rated Sheathing panels are assessed for performance as sheathing in roofs, subfloors and walls. Panels are assigned a Span Rating, which is primarily a mea- sure of panel stiffness and strength paral- lel to the major panel strength axis (usually the long dimension).
