* Requires additional concrete strength at Transfer.

Notes:

Load Charts are intended for preliminary design only.
Max tension under full loading = 850 psi.
Design criteria ACI 318-02.
Concrete strength at 28 days (f`c) = 6000 psi.
Design charts assume simple span.
Loading is based on 3 in., 4000 psi composite topping.
Deflections must be checked according to design criteria.
