Type definition

Defines the different predefined types of ground reinforcement elements that can specify an IfcGroundReinforcementElement.

Enumeration definition

Constant	Description
PILE	A slender structural element driven, jetted or otherwise embedded into the ground to reinforce and stabilise the ground by increasing the shear resistance of the ground through bending and/or shear of the pile, as opposed to an IfcPile where these piles are primarily vertically loaded.
TUBE	A hollow, cylindrical structural element that is drilled, driven or otherwise embedded into the ground to reinforce and stabilise the ground by increasing the shear resistance of the ground through bending, shear and/or tension of the tube.
BAR	A solid, cylindrical structural element that is drilled, driven or otherwise embedded into the ground to reinforce and stabilise the ground by increasing the shear resistance of the ground through bending, shear and/or tension of the bar.
PLATE	A solid, twin rectangular structural element that is drilled, driven or otherwise embedded into the ground to reinforce and stabilise the ground by increasing the shear resistance of the ground through bending, shear and/or tension of the plate.
BOLT	A solid or hollow cylindrical structural element installed in the ground through drilled holes to reinforce and stabilise the ground through tension in the bolt. The bolt usually includes an anchor plate with bolt and is bonded to the ground either by a mechanically expanding end anchorage, friction along its length or grouting along its length. It is generally untensioned, but may be tensioned if required.
TENDON	A high-strength steel or fiberglass cable installed in the ground through drilled holes to reinforce and stabilise the ground through tension in the tendon. The tendon usually has a mechanical anchor at the open end of the tendon and a fixed grouted length at the end of the tendon in the ground. It is generally tensioned.
FABRIC	Geotextiles or geosynthetic materials embedded in the ground to reinforce and stabilise the ground by increasing the shear resistance of the ground through tension in the fabric.
USERDEFINED	User-defined type.
NOTDEFINED	Undefined type.
