Smart combinations: how to use them and what they do
The smart combination facility allows a user to select a number of loadcases from the available results, and associate two load factors with each: "permanent" and "variable" factors.
Using the menu item:
Utilities > Combination > Smart combination
OR Bridge > Loading combinations
generates two load combinations in the TreeView (similar to the envelope facility). One is for maximum positive (Max) load effects, and one for maximum negative (Min) load effects.
On the smart combination dialog box, there also exist two check boxes: "Loadcases to consider" and "Variable
loadcases". These are intended for advanced users and activate functions which are applicable in a small number of international standards. They are not generally applicable for UK codes of practice, for example.
