Navigation:  Working With Beam Calculations > Beam Loads > Live Load Reduction > Adding or Modifying Loads in ENERCALC SEL

It is advisable for users to remain aware of whether live load reduction is currently active in an ENERCALC SEL calculation at any given time.  Although there is not a direct indication of reduction status within the ENERCALC SEL interface, the reduction settings are managed during calculation launch from Revit as previously described.

NOTE:  Any live loads (LL) or roof live loads (LR) that are added or modified from the ENERCALC SEL interface while LL or LR reduction is active in a calculation will be treated as REDUCED magnitudes.  This load will then be created or updated in the Revit model with an “unreduced” magnitude obtained by dividing the reduced magnitude by the applicable reduction factor.

This process prevents loads from being stored in the Revit model with a magnitude that reflects code provisions unique to only one specific element and allows loading in the Revit model to remain valid even when the LL reduction settings on various elements change over time.

If this behavior is undesirable, loads may be modified directly from the Revit model, or from ENERCALC SEL calculations where LL reduction is not activated.

In the example below, a calculation for a floor beam supporting long-span deck is launched with LL reduction activated.  

Since LL reduction was activated during launch, all LL magnitudes displayed in the ENERCALC SEL interface are reduced.

If this live load magnitude is manually modified by the user, the newly revised magnitude is treated as a reduced magnitude.

This will result in the underlying area load in the Revit model being updated to a magnitude of:

LL = (0.08 Ksf) / 0.817 = 0.09792 Ksf
