By selecting the “Notional Loads from Load Case” imperfection type, you can define the equivalent loads for an imperfection case yourself.
To do this, select a load case in the "Notional Loads from Load Case" tab or create a new load case using the
button. You can only use load cases without an action category, as these are not included in the combinatorics.
In contrast to member imperfections, which are also considered using equivalent loads, you can apply any loads independent of the axial force in the selected load case.
Calculation
When calculating a load case or a load combination with this imperfection type, the equivalent loads are taken into account in addition to the existing load.
It is not possible to calculate the imperfection case of the “Notional Loads from Load Case” type. To estimate the effect, you can calculate the original load case instead.
