Sheathing Input

Important Note – These are descriptions to changes implemented in WoodWorks Shearwalls for version 9 and may not reflect current behavior.

The following inputs have been added to access SDPWS Table C4.2.2A for shear deflection ( ).

1. Span rating

   The program allows for selection of span rating in order to access table C4.2.2A

   1. Alternative thicknesses

      Note that shearwalls has not added plywood thickness inputs for those thicknesses ( ½ , 5/8, and ¾) that are only alternative thicknesses in Table C4.2.2C. The thicknesses in Shearwalls are minimum thicknesses for shearwall design. You can type in a different thickness, and the program will use the next smallest standard thickness for design. This is legitimate for deflection design as well, as the next smallest primary thickness to the alternative thickness has the set of possible same span ratings according to Table C4.2.2.C, and those appear in the span rating drop down when these thicknesses are typed in.

2. OSB

   A checkbox has been added to allow you to specify that the material is OSB as opposed to plywood, which has different G_vt_v values in in Table C4.2.2A..

3. Number of Plies

   You can now select the number of plywood plys, 3, 4, or 5, which have different G_vt_v values in in Table C4.2.2A. This input is disabled for OSB.
