# 6.6.5 *Redistribution of Moments in Continuous Flexural Members*

JUMP TO FULL CODE CHAPTER

Except where approximate values for moments are used in accordance with 6.5, where moments have been calculated in accordance with 6.8, or where moments in two-way slabs are determined using pattern loading specified in 6.4.3.3, reduction of moments at sections of maximum negative or maximum positive moment calculated by elastic theory shall be permitted for any assumed loading arrangement if (a) and (b) are satisfied:

(a) Flexural members are continuous

(b) **ε _{t} ≥ 0.0075** at the section at which moment is reduced

For prestressed members, moments include those due to factored loads and those due to reactions induced by prestressing.

At the section where the moment is reduced, redistribution shall not exceed the lesser of

**1000ε**percent and 20 percent._{t}The reduced moment shall be used to calculate redistributed moments at all other sections within the spans such that static equilibrium is maintained after redistribution of moments for each loading arrangement.

Shears and support reactions shall be calculated in accordance with static equilibrium considering the redistributed moments for each loading arrangement.
