Definition from buildingSMART International: This type definition is used to distinguish
between different kinds and purposes of load grouping. It allows to
differentiate between load groups, load cases, load combination groups and load
combinations. Normally, these enumeration types shall be used in the following
- LOAD_GROUP groups instances of IfcStructuralAction or its
subclasses. It shall be used as a container for loads grouped together for
specific purposes. Optionally, an overall load factor can be assigned.
- LOAD_CASE groups LOAD_GROUPs and instances of
IfcStructuralAction or its subclasses. It shall be used as a container
for loads with the same origin, and to assign a common load factor.
- LOAD_COMBINATION_GROUP shall be used to group LOAD_CASEs and to
assign a common load combination factor. The grouping of LOAD_GROUPs and
instances of IfcStructuralAction or its subclasses is also possible, but
off the traditional way.
- LOAD_COMBINATION shall be used to group all loads belonging to a
specific load combination. Normally only LOAD_COMBINATION_GROUPs with all
needed load factors are used to create load combinations.
