Tables to Design Wall Forms
An alternate method for designing wall forms is to use tables, such
as those that have been developed by the APA—The Engineered
Wood Association or by companies in the construction industry that
supply formwork products. Tables are available that provide the
allowable span length of plywood for a given concrete pressure. The
design simply involves selecting the allowable concrete pressure
based on the species and stress rating of the plywood, or selecting
the allowable span length of framing lumber to support plywood
sheathing.
Examples of these types of tables are presented in Chapter 4 for
Plyform, which is manufactured by the plywood industry specifically
for use in formwork for concrete. Tables 9-7 through 9-10 are reproduced
in the following sections from Chapter 4 for application to the
design of wall forms. When the design of formwork is based on design
tables of manufacturers or associations in the construction industry, it
is important to follow their recommendations.
