WebNotional loads (NL) are automatically derived from the factored loadcases within the current combination. They are applied in the analysis as a horizontal force at each beam column … WebMay 2, 2007 · Some people are doing this instead of applying the notional load. In some cases, you can get away with applying the notional loads only to gravity-only LCs. The ELM confusion comes from C2.2a (3) which seems to clearly indicate that a notional load is only applied to gravity-only combinations.

Notional loads are required to be applied. If the ratio of 2 nd order drift to 1 st order drift (i.e., B 2) is greater than 1.5, the notional loads must be applied in addition to the other lateral loads (wind and seismic); if the ratio is less than 1.5, it is permissible to apply the notional loads to the gravity-only combinations.
