Classes

Groups LOAD_GROUPs and instances of subtypes of [[IfcStructuralAction]].; It should be used as a container for loads with the same origin.

An intermediate level between LOAD_CASE and LOAD_COMBINATION. This level is obsolete and deprecated. Before the introduction of IfcRelAssignsToGroupByFactor, the purpose of this level was to provide a factor with which one or more LOAD_CASEs occur in a LOAD_COMBINATION.

Groups instances of subtypes of [[IfcStructuralAction]]. It shall be used as a container for loads grouped together for specific purposes, such as loads which are part of a special load pattern.

A load case is a load group, commonly used to group loads from the same action source.

The entity [[IfcStructuralLoadGroup]] is used to structure the physical impacts. By using the grouping features inherited from [[IfcGroup]], instances of [[IfcStructuralAction]] (or its subclasses) and of [[IfcStructuralLoadGroup]] can be used to define load groups, load cases and load combinations. (See also IfcLoadGroupTypeEnum.)
