Notes:

Load Charts are intended for preliminary design only.
Other section available. Consult MBI Engineering Department.
Max tension allowed under full loading = 850 psi, therefore, additional top reinforcement is required.
Design criteria ACI 318-02
Concrete strength at 28 days (f`c) = 6000 psi
Design charts assume simple span
Safe loads shown include 50% dead load and 50% live load
Deflections must be checked according to design criteria
Beams design includes an additional 3 topping 4000 psi. composite
