Several sub load cases per load group are a way to organize variations of a certain load group.
For example: the wind can blow from different directions. You could made a load group Wind for each direction, but you could also define one load group Wind and define the 4 directions in the same load group. Assume there are 4 wind directions to be taken into account. Then you do the following in Diamonds:
- Add one load group for wind.
- Check the option Several load cases per group.
- Increase the number of load case to four. Diamonds will add Case 1, Case 2, Case 3 and Case 4 automatically to the list. You can change the name of the case if you’d like.
- The little guys define the incompatbility. When you click on the icon the little guys can hold hands or not.
- if they are not holding hands, it means the sub load cases are incompatible. Meaning they cannot occur at the same time. This is particularly the case for wind/ snow loads.
- if they are holding hands , it means all sub load cases will act on the structure at the same time. This is particularly the case for dead loads.
