RAM Concept uses up to six parameters to determine the allowed reduction factors:

Loading type - Only certain loading types may be reduced (as is discussed above)

Member type - Most codes have special reduction rules for certain member types (such as columns)

Maximum allowed reduction - The user may specify a maximum reduction value for each member.

Number of levels supported - Most codes consider the number of levels supported when calculating the allowed reductions. If RAM Concept's automatic calculation of areas is used, then the number of levels supported is assumed to be one.

Tributary area - Most codes use the tributary area of the member as the primary live load reduction parameter.

Influence area - RAM Concept has options for two codes that use the influence area of the member as the primary live load reduction parameter.

RAM Concept calculates the last three parametric values. You can view the values on plan as described in "To view the column element LLR results" and "To view the latitude design strip LLR results".

You can override the calculation by specifying the parameters’ values. The next section describes how to edit these values.
