>>UBC 97, Tables 23-II-E-1 7 23-II-E-2 refer to the strength axis of plywood
panels. Which is the strength axis? Assuming an 8x4 panel is the strength axis
parallel to the 8 foot side or the 4 foot side?

The way I read these tables plywood is stronger when the 8 foot side is
parallel to the supports. Is this correct?<<


Plywood has greater strength when its face grain direction is perpendicular 
to the supports.
