Formwork Design Tables - EXAMPLE Flat Slab
SHEATHING
- Shore spacing places the stringers 4 ft apart, and this 4 ft then is the span of the joists. How joists are spaced depends on requirements of the sheathing.
- Assume 3/4-in. Plywood Class I or equal quality plywood is used with its face running in the direction of the span.
- Since sheathing is continuous over several spans, refer to Table 7-2.
- The right side of the table, with F’V = 1545 psi, applies since this is a multiple-use form.
