BS 6399 live load reduction is specified in code sections 6.1 through 6.3.

Only live loadings with the "Live (Reducible)" type are reduced.

For columns, the Table 2 and Table 3 values from the code are calculated and the greater of the two reductions is used. For other members, the Table 3 values are used.

For columns, the moment and shear values are reduced by the same reduction factor as the axial force values; this is different from what is specified in the note in Section 6.2 of BS 6399. This does not affect any design in RAM Concept (or the RAM Structural System), but it does affect the reported column reaction values.

Live load reduction is not used for one-way and two-ways slabs.
