This enumeration identifies different types of building systems.
6.1.2.5.2 Type values
| Type | Description |
|---|---|
EROSIONPREVENTION
|
A grouping of elements into a built system for preventing unwanted relocation of material particles in earthworks slopes or rock faces. Typical types of erosion prevention include: * Planting * Solid * Framework * Anchored framework * Shotcrete * Screening * Geosynthetics (geotextiles) |
FENESTRATION
|
System of doors, windows, and other fillings in openings in a built envelope that are designed to permit the passage of air or light. |
FOUNDATION
|
System of shallow and deep foundation element that transmit forces to the supporting ground. |
LOADBEARING
|
System of built elements that transmit forces and stiffen the construction. |
OUTERSHELL
|
System of built elements that provide the outer skin to protect the construction (such as the facade). |
PRESTRESSING
|
System of elements providing pre-stressing to the structure, including typically manufactured products such as tendons, anchorages (active, dead, coupling), ducts, vents and deviators, and in-situ concrete segments, tendon spacers, blisters and additional reinforcements. |
REINFORCING
|
System of elements providing reinforcing to the structure. |
SHADING
|
System of shading elements (external or internal) that permits the limitation or control of impact of natural sun light. |
TRANSPORT
|
System of all transport elements in a building that enables the transport of people or goods. |
