Has anyone ever built stress skin platforms wider than 4'? Say a 5' x 5' or larger. Did you simply run the splice plate parallel with the grain and offset the splice for the top skin and bottom skin so that the seam doesn't fall in the same place for the whole platform? I was checking out the PDS Supplement no 3 on stressed skin panels and noticed the examples were all 4' wide. The only time it mentions over 4' wide is in near the calculations sections and that the tables would have to be readjusted for panels wider that 4'.
