+
+### StructuralElement
+
+The abstract class `StructuralElement` is the generalization of `StructuralMember`.
+
+Equivalent to [IfcStructuralItem](https://standards.buildingsmart.org/IFC/RELEASE/IFC4_3/HTML/lexical/IfcStructuralItem.htm).
+
+### StructuralMember
+
+The class `StructuralMember` is the base class of all structural items. This class is not abstract and could be used to define any generic structural element, but it is recommended to use any defined subclass if available. `StructuralMember` instances must be contained in `PhysicalModels`.
+
+Classification of `StructuralMember` instances can be achieved via instances of `StructuralMemberType`.
+
+`StructuralMember` should be used as a base of any specialized class.
+
+Equivalent to [IfcStructuralMember](https://standards.buildingsmart.org/IFC/RELEASE/IFC4_3/HTML/lexical/IfcStructuralMember.htm).
+
+### StructuralMemberType
+
+`StructuralMemberType`s must be contained in `DefinitionModel`s.
+
+Equivalent to [IfcMemberType](https://standards.buildingsmart.org/IFC/RELEASE/IFC4_3/HTML/lexical/IfcMemberType.htm).
+
+### Slab

+
+Classification of `Column` instances can be achieved via instances of `ColumnType`. `Column`s must be contained in `PhysicalModel`s.
+
+Equivalent to [IfcColumn](https://standards.buildingsmart.org/IFC/RELEASE/IFC4_3/HTML/lexical/IfcColumn.htm).
+
+### ColumnType
+
+`ColumnType`s must be contained in `DefinitionModel`s.
+
+Equivalent to [IfcColumnType](https://standards.buildingsmart.org/IFC/RELEASE/IFC4_3/HTML/lexical/IfcColumnType.htm)
+
+### Brace
+
+A `Brace` is a structural member designed to provide lateral support to a structure, ensuring stability by resisting sideways forces. It typically serves as a diagonal element, connecting to other members. As an `StructuralMember`, it contributes to the overall integrity and rigidity of the structural system for load-bearing purposes.
+
+Classification of `Brace` instances can be achieved via instances of `BraceType`. `Brace`s must be contained in `PhysicalModel`s.
+
+Equivalent to [IfcMember](https://standards.buildingsmart.org/IFC/RELEASE/IFC4_3/HTML/lexical/IfcMember.htm) with a PredefinedType equal to [IfcMemberTypeEnum](https://standards.buildingsmart.org/IFC/RELEASE/IFC4_3/HTML/lexical/IfcMemberTypeEnum.htm).BRACE.
+
+### BraceType
+
+`BraceType`s must be contained in `DefinitionModel`s.
+
+Equivalent to [IfcMemberType](https://standards.buildingsmart.org/IFC/RELEASE/IFC4_3/HTML/lexical/IfcMember.htm) with a PredefinedType equal to [IfcMemberTypeEnum](https://standards.buildingsmart.org/IFC/RELEASE/IFC4_3/HTML/lexical/IfcMemberTypeEnum.htm).BRACE.
+
+### FoundationMember
+
+An `FoundationMember` is a foundational structural element designed to transfer building loads to the ground. It serves as a base class within the structural hierarchy, providing essential support and stability to the entire structure. This class is further specialized into specific types of foundation members, such as footings or piles, which are tailored to meet particular load-bearing and ground conditions. As a fundamental component, it ensures the safe and efficient transfer of loads from the structure above to the supporting ground below.
+
+### StripFooting
+
+A `StripFooting` is a type of shallow foundation element designed to support a linear structure, such as a wall. It is a continuous strip of concrete that spreads the load of the wall over a wider area, reducing the stress on the soil. This type of footing is used to ensure the stability and support of the wall, particularly in load-bearing walls, making it a critical component in building foundations.
+
+Classification of `StripFooting` instances can be achieved via instances of `StripFootingType`. `StripFotting`s must be contained in `PhysicalModel`s.
+
+Equivalent to [IfcFooting](https://standards.buildingsmart.org/IFC/RELEASE/IFC4_3/HTML/lexical/IfcFooting.htm) with a PredefinedType equal to [IfcFootingTypeEnum](https://standards.buildingsmart.org/IFC/RELEASE/IFC4_3/HTML/lexical/IfcFootingTypeEnum.htm).STRIP_FOOTING.
+
+### StripFootingType
+
+`StripFootingType`s must be contained in `DefinitionModel`s.
+
+Equivalent to [IfcFootingType](https://standards.buildingsmart.org/IFC/RELEASE/IFC4_3/HTML/lexical/IfcFootingType.htm) with a PredefinedType equal to [IfcFootingTypeEnum](https://standards.buildingsmart.org/IFC/RELEASE/IFC4_3/HTML/lexical/IfcFootingTypeEnum.htm).STRIP_FOOTING.
+
+### SpreadFooting
+
+An `SpreadFooting` is a type of shallow foundation element that distributes the load of a column over a broad area. It usually consists of a concrete pad that spreads the weight of the column onto the ground below, reducing the stress on the soil. This type of footing is designed to ensure stability and support for the column, making it an essential component in building foundations.
+
+Classification of `SpreadFooting` instances can be achieved via instances of `SpreadFootingType`. `SpreadFooting`s must be contained in `PhysicalModel`s.
+
+Equivalent to [IfcFooting](https://standards.buildingsmart.org/IFC/RELEASE/IFC4_3/HTML/lexical/IfcFooting.htm) with a PredefinedType equal to [IfcFootingTypeEnum](https://standards.buildingsmart.org/IFC/RELEASE/IFC4_3/HTML/lexical/IfcFootingTypeEnum.htm).PAD_FOOTING.
+
+### SpreadFootingType
+
+`SpreadFootingType`s must be contained in `DefinitionModel`s.
+
+Equivalent to [IfcFootingType](https://standards.buildingsmart.org/IFC/RELEASE/IFC4_3/HTML/lexical/IfcFootingType.htm) with a PredefinedType equal to [IfcFootingTypeEnum](https://standards.buildingsmart.org/IFC/RELEASE/IFC4_3/HTML/lexical/IfcFootingTypeEnum.htm).PAD_FOOTING.
+
+### PileCap
+
+A `PileCap` is a reinforced concrete slab that rests on top of multiple piles and distributes the loads from the superstructure evenly across the piles. It acts as a foundation component to ensure stable support by connecting the piles and transferring the load from the building or structure above to the deeper, more stable soil or rock layers beneath.
+
+Classification of `PileCap` instances can be achieved via instances of `PileCapType`. `PileCap`s must be contained in `PhysicalModel`s.
+
+Equivalent to [IfcFooting](https://standards.buildingsmart.org/IFC/RELEASE/IFC4_3/HTML/lexical/IfcFooting.htm) with a PredefinedType equal to [IfcFootingTypeEnum](https://standards.buildingsmart.org/IFC/RELEASE/IFC4_3/HTML/lexical/IfcFootingTypeEnum.htm).PILE_CAP.
+
+### PileCapType
+
+`PileCapType`s must be contained in `DefinitionModel`s.
+
+Equivalent to [IfcFooting](https://standards.buildingsmart.org/IFC/RELEASE/IFC4_3/HTML/lexical/IfcFootingType.htm) with a PredefinedType equal to [IfcFootingTypeEnum](https://standards.buildingsmart.org/IFC/RELEASE/IFC4_3/HTML/lexical/IfcFootingTypeEnum.htm).PILE_CAP.
+
+### Pile
+
+A `Pile` is a slender structural element made of timber, concrete, or steel, driven, jetted, or embedded into the ground to support a load. It is classified as a deep foundation, transferring loads to deeper subsurface layers for enhanced stability and support.
+
+Classification of `Pile` instances can be achieved via instances of `PileType`. `Pile`s must be contained in `PhysicalModel`s.
+
+Equivalent to [IfcPile](https://standards.buildingsmart.org/IFC/RELEASE/IFC4_3/HTML/lexical/IfcPile.htm).
