WebThe program will create the following load combination for the calculation of λ cr: 1.2ND + 1.2NL, where ND = Notional Dead Load and NL = Notional Live Load. Note that the original (gravity and lateral) load cases are not considered in the combination used to determine λ cr but the appropriate load case factors are. WebA notional load is a fictitious lateral load applied in a structural analysis as a means to account for the destabilizing effects of gravity loads that are not otherwise accounted for in design provisions.

WebNotional loading (equivalent horizontal forces) are loads resulting from inaccuracies and imperfections introduced into the structure during its construction. This note explains … WebJan 20, 2005 · The notional load was conceived for the case where there was no lateral load to begin with. If there is already significant lateral load on the column, then you may not need another (2%-10%)*Pu. On the other hand, adding in some extra moment load in the column is not a bad idea given the uncertainty of lateral loads, esp EQ.
