Imposed Loads are referred to in the program and documentation as "Live Loads". Live Loads specified as Reducible are reduced as allowed by BS 6399: Part 1: 1996 Clause 6, "Reduction in total imposed floor loads", as described below. Note that the UK National Annex to Eurocode 1 (NA to BS EN 1991-1-1:2002) uses this same methodology.

For columns, Live Loads specified as Reducible are reduced by the greater of Table 2 and Table 3. In the determination of Number of Floors used in Table 2, the user may specify that only floors carrying Reducible Live Load be included in that number by invoking the Criteria > Live Load Reduction Command in the RAM Manager as explained previously.

The Code explicitly requires that, when the Live Load is reduced, the Live Load Reduction Factor used on column moments is that corresponding to the beam which creates the moment, while the Live Load Reduction Factor used on column axial load is that corresponding to the column itself. As a simplification, the program only reduces the column axial load; it does not reduce the column moments. Since beam Live Load Reductions are small (generally about 2 to 5%), this is not likely to have a significant impact on the design, and is conservative.

Reducible Live Loads on beams are reduced per Table 3. Reductions for intermediate areas are calculated by linear interpolation.

For transfer girders, the reduction of the point load from the column is that of the column itself, and the reduction of the remaining Live Loads is based on the supported area not including that coming from the column.

Live Loads specified as Roof loads are reduced based on the slope of the roof in the vicinity of the member per BS 6399:Part 3:1988 Clause 4.3.1. If the slope is less than 30 degrees no reduction is taken. If the slope is greater than 60 degrees the load is completely reduced (to 0.0). For intermediate slopes the percent reduction is interpolated.

No reduction is made on Live Loads specified as Unreducible or Storage.

It is important to note that the output lists the reduction as a percent by which the load can be reduced, rather than as a load multiplier.
