) multiplied by load factors does not exceed the nominal reduced flexural resistance ( ) of your concrete cross-section.

Ensure your math engine evaluates the structure under maximum and minimum permanent load factors simultaneously. For instance, maximum vertical earth load combined with minimum lateral earth load often yields the worst-case positive bending moment in the top slab. Fix the dimensions (Span x Rise) based on

Are the 45-degree haunches included in the moment of inertia calculations?

from the face of the support, rather than at the centerline of the joint. For instance, maximum vertical earth load combined with

inch fillets are required; adjust the clear span dimensions in your calculations accordingly.

) on the top slab, compute the fixed-end moments assuming rigid corners prior to distribution:

b⋅t312the fraction with numerator b center dot t cubed and denominator 12 end-fraction ). Use these values to fix the distribution factors ( DFcap D cap F ) at the joints:
