Forms for Walls 221
9. Studs and wales will be 2-in. nominal framing.
10. Lumber will be No. 2 grade Southern Pine (refer to Table 9-2).
11. Sheathing will be 3/4-in. Plyform (refer to Tables 9-3 and 9-4).
Figure 9-2 provides an illustration of the span lengths and spacing
of components for the wall form. Tables 9-5 and 9-6 provide the equations
that are necessary to design the wall forms. The design will be
performed in the following sequence:
1. Determine the maximum lateral pressure of the concrete on the
wall forms based on temperature and rate of filling the forms.
2. Determine the spacing of studs based on the strength and
deflection of plywood sheathing.
