Column corbel (Geometry)

Column corbel property	Description
Icon
Modules where available
Function	It models corbels attached to columns.
Position	Horizontal, perpendicular to the local y’ or z’ axis of the column it is attached to.
Geometry	Straight
Cross-section	Arbitrary profile
End connection	Always rigid at the column it is attached to (Start). Arbitrary at the end point, set by the object attached to the corbel.
Material	Concrete, steel, timber
Load direction	Arbitrary in
Load type	All point and line load in
Available analysis results	Displacement, internal forces, stresses, stability and vibration shape in
Alternative	Can be considered as eccentricity of the load acces point on the column, or can be modelled as a short beam with the suitable end conditions and eccentricity.
Default Short Command	CCOR

Definition steps

1. Start  Column corbel command from   Bar component menu in  tabmenu
2. Set the direction of the Column corbel. A Column corbel is always perpendicular to the local x’ axis and parallel with the local y’ or z’ axis of the column.
   
3. Set the properties of the new column corbel at  Default settings: 
   
   • Identifier (General)
     The program automatically generates it, but User can define custom value. Identifier (ID and Position) number can be displayed in model view (Display settings).
   • Geometry (General)
     User can specify the followings:
     • direction of the Corbel
     • relative position of the Corbel compared to the column (d, e)
     • length of the Corbel (l)
     • position of the load application point (x, e), marked with red dot in the figure below
     • whether to calculate the “d” value automatically in accordance with the Section of the column or not
       
   • Section
     User can set a profile from the Section library or define a new cross-section by parameters. The applied section name can be displayed in model view (Display settings).
   • End conditions
     In 3D modules, the end connections can be set under the End conditions tab. Only the released motion (arrow) and rotation (two-headed arrow) components are displayed in the model view (Display settings). End connections can be fully customised for bar ends by setting the rigidity of the displacement components.
     The component directions are valid in the beam’s local co-ordinate system.
     Inactive component means a fixed motion/rotation, while a checked component behaves according to the user-specified rigidity value.
     
     
     With the „Rigid” and the „Hinged” buttons pre-defined end condition values can be applyed to the bar ends.
     The local x’ axis always points the vertical fictitious bar end, so the start and end point position can be followed from the bar’s local co-ordinate system.
     
     
     Only the released motion (arrow) and rotation (two-headed arrow) components are displayed in the model view (Display settings).
   • Material
     Any type of materials can be set for corbel Analysis. The applied material name can be displayed in model view (Display settings).
4. Place the corbel along a column by left-clicking.

Optional steps:

5. Modify the Corbel properties with the  Properties tool of the Corbel tool palette.
6. Set the display settings of Corbel at Settings > All > Display > Bar similarly to Beams.
7. Corbels are stored on “Columns” Object layers. At layer settings, the default color and pen width can be set for all columns and corbels.
