Using the result class

Result classes may be used to view the effect of certain "combinations" of load cases and load case combinations. They are offered in all dialogues for results review together with load classes and load class combinations.

Important notes relating to result classes

If no result class is defined manually by the user, the program generates three classes automatically when opening any result or check service or during the run of check structure command:

- class containing all existing ULS combinations

- class containing all existing SLS combinations

- class containing all existing ULS and SLS combinations

Note: For EC-EN, combinations of the type EN-ULS (STR/GEO) Set C are NOT added into any of the three automatically generated classes. Also, such combination cannot be added there later. This specific combination type is added into a special Geotechnics class as explained further below.

If some result classes are defined manually by the user before, no automatic classes are generated.

 

If the user creates a result class that contains ALL load case combinations of a certain type existing at the moment when the class is being created, the program assumes that it is the intention to have all the combinations of that type in the class in question. Therefore, if the user later creates a new combination of the same type, it is automatically added to the corresponding result class.

This rule applies to both manually and automatically created result classes.

This rule implies also the following behaviour of the program. Let us assume that the three automatic result classes were generated. Now, the user changes the type of one of the existing combinations (let us say) from SLS to ULS. The newly appearing ULS combination is automatically added to the  result class with all the ULS combinations. However, the combination ALSO REMAINS in the result class with all the SLS combinations (this issue is handled at the moment and the behaviour of the program may change in one of the following versions in respect to this particular feature).

Also result class GEO for geotechnics according to EC-EN is automatically generated. This result class is generated immediately after the calculation has been completed and requires that the Subsoil functionality - Pad foundation check be switched ON.

The GEO class contains all code combinations of the following types:

- EN-ULS (STR/GEO) Set B

- EN-ULS (STR/GEO) Set C

Examples

Combination key of linear combination within one result class

In case there is a result class RC1, which contains only linear combinations (as in example below), and some results are provided for this result class for the "result table" or the "report preview", in the column "case", there is a number after "/" symbol for each of these linear combinations, e.g. below ULS-Set B(auto)9/1.

This number "/1" indicates the combination key as summarized in the table of the combination keys below. The numbering of these combination keys goes through whole the list of the linear combinations. So, it does not mean this is the first key of that particular combination (as there is only one key for each linear combination), but first key of all the keys (from all the combinations).
