Apa and three other independent labs have conducted nearly 100 cyclic tests 1 showing that the 16 inch wide portal frame design used in a continuously sheathed wood structural panel wall with a 6 1 aspect ratio as measured at the vertical wall segment performs comparably to wood structural panel wall bracing segments currently permitted in the irc.
Also sheathed areas narrower than 4 feet may be counted as braced wall panels minimum width depends on the height of the wall and the height of adjacent openings.
