79 Moment Redistribution

The moment values of a continuous beam obtained from structural analysis may be adjusted or redistributed according to guidelines set by ACI 8.4. Negative moment can be adjusted down or up, but not more than 1000et or 20% (see Notation section for et). After the negative moments are adjusted in a span, the positive moment must also be adjusted to maintain the statical equilibrium of the span (see Section 7.13.12). Redistribution of moment is permitted to account for the ductile behavior of reinforcement concrete members.
