Load Span
Tables
1. Form Panel
Thickness
Strength and stiffness are greatest
when applied with face grain across supports. Table 1
shows the required panel thickness when applied in this
manner. When applied with face grain parallel to
supports, the required thickness may be determined from
Table 2. For more detailed design information, refer to
American Plywood association "Plywood For Concrete
Forming" and to American Concrete Institute "Formwork
for Concrete."
2. Edge Support
Under conditions of high
moisture or sustained load to the panel, edges may have
a greater deflection than the center of the panel and
may exceed calculated deflection unless panel edges are
supported.
3. Special Engineered Systems
Tables 1
& 2 herein are based on standard APA and commercial
standards PS-1 criteria. However certain Olympic Panel
customers and engineered concrete form system
manufacturers may publish different span tables based on
their own system tests, field conditions and experience.
