−	~~there~~ may be ~~differences in~~ the ~~impact~~ of ~~alcohol on~~ the ~~brains~~ of ~~teenage girls~~ and ~~boys who drink~~	+	Approved document B, Fire Safety, Volume 2, Buildings other than dwellinghouses (2019 edition), suggests an ‘element of structure’ is any of the following:
		+
		+	* A member that forms part of the structural frame of a building, or any other beam or column.
		+	* A loadbearing wall or loadbearing part of a wall.
		+	* A floor.
		+	* A gallery (but not a loading gallery, fly gallery, stage grid, lighting bridge, or any gallery provided for similar purposes or for maintenance and repair).
		+	* An external wall.
		+	* A compartment wall (including a wall that is common to two or more buildings).
		+
		+	The guidance to requirement B3, paragraph 6.2, lists structures that are not considered to be elements of structure:
		+
		+	* A structure that supports only a roof, unless either of the following applies.
		+
		+	# The roof performs the function of a floor, such as for parking vehicles, or as a means of escape.
		+	# The structure is essential for the stability of an external wall that needs to be fire resisting (e.g. to achieve compartmentation or for the purposes of preventing fire spread between buildings).
		+
		+	* The lowest floor of the building.
		+	* A platform floor.
		+	* External walls, such as curtain walls or other forms of cladding, which transmit only self weight and wind loads and do not transmit floor load.
		+
		+	NOTE: In some cases, structural members within a roof may be essential for the structural stability system of the building. In these cases, the structural members in the roof do not just support a roof and must demonstrate the relevant fire resistance for the building as required by the note to paragraph 6.1 (If one element of structure supports or stabilises another, as a minimum the supporting element should have the same fire resistance as the other element).

−	~~[http://www.planningportal.gov.uk/buildingregulations/approveddocuments/partb/bcapproveddocumentsb/bcapproveddocbvol2/~~ Approved document B, Fire Safety, Volume 2, Buildings other than dwellinghouses], ~~paragraph B3.iii defines ‘elements~~ of structure’ ~~as:~~	+	Approved document B, Fire Safety, Volume 2, Buildings other than dwellinghouses (2019 edition), suggests an ‘element of structure’ is any of the following.

−	~~…the term applied to~~ the ~~main~~ structural loadbearing elements, such as structural frames, floors and loadbearing walls. Compartment walls are treated as elements of structure although they are not necessarily loadbearing. Roofs, unless they serve the function of a ~~floor~~, ~~are not treated as elements of structure~~.	+	* A member that forms part of the structural frame of a building, or any other beam or
		+	* column.

−	~~External walls, such as curtain walls~~ or ~~other forms of cladding which transmit only self weight and wind loads and do not transmit floor load, are not regarded as~~ loadbearing ~~for the purposes~~ of ~~B3.ii(~~a~~), although they may need fire resistance to satisfy requirement B4 (see Sections 8 to 9)~~.	+	* A loadbearing wall or loadbearing part of a wall.
		+	* A floor.

−	~~Loadbearing elements may or may~~ not ~~have~~ a ~~fire-separating function. Similarly~~, ~~fire-separating elements may~~ or ~~may not be loadbearing~~.	+	* A gallery (but not a loading gallery, fly gallery, stage grid, lighting bridge, or any gallery provided for similar purposes or for maintenance and repair).

−	~~Notes:~~	+	* An external wall.

−	* ~~B3.ii~~(a~~) refers~~ to ~~the resistance to collapse, i.e. the ability to maintain loadbearing capacity (which applies to loadbearing elements only~~).	+	* A compartment wall (including a wall that is common to two or more buildings).
−	* B4 refers to 'external fire spread' and requires that:	+

−	# The ~~external walls of the building shall adequately resist the spread of fire over the walls and from one building~~ to ~~another~~, ~~having regard to the height, use and position of the building~~.	+	The guidance to requirement B3, paragraph 6.2, lists structures that are not considered to be elements of structure:
−	~~# The roof of the building shall adequately resist the spread of fire over the roof and from one building to another~~, ~~having regard~~ to ~~the use and position~~ of ~~the building.~~	+

−	* ~~Section 8 relates~~ to compartmentation.	+	* A structure that supports only a roof, unless either of the following applies.
−	* ~~Section 9 relates~~ to ~~concealed spaces~~ (~~cavities~~).	+
		+	# The roof performs the function of a floor, such as for parking vehicles, or as a means of escape.
		+	# The structure is essential for the stability of an external wall that needs to be fire resisting (e.g. to achieve compartmentation or for the purposes of preventing fire spread between buildings).
		+
		+	* The lowest floor of the building.
		+	* A platform floor.
		+	* External walls, such as curtain walls or other forms of cladding, which transmit only self weight and wind loads and do not transmit floor load.
		+
		+	NOTE: In some cases, structural members within a roof may be essential for the structural stability system of the building. In these cases, the structural members in the roof do not just support a roof and must demonstrate the relevant fire resistance for the building as required by the note to paragraph 6.1 (If one element of structure supports or stabilises another, as a minimum the supporting element should have the same fire resistance as the other element).
