Modify the analytical properties of the structural column to accommodate structural analysis tools and procedures.
To change structural analytical properties, select the element. In the Properties palette, select the element specific analytical properties from the Properties filter.
| Name | Description |
|---|---|
| Analytical Model | |
| Analyze As | Either Hanger, Gravity, or Lateral analysis. Used by external analysis applications to determine whether the column contributes to lateral analysis. |
| Analytical Links | A frame element that can be set to fully rigid or released in global directions. When Analytical Links are enabled, an additional analytical segment is engaged in the model between the end of the analytical model of a beam and the analytical model of a column.
See Analytical Link. |
| Analytical Properties | |
| Family Type | The family type of the element. |
| Physical Material Asset | The name of a physical asset assigned to the column material (read-only). |
| Length | The length of the analytical model. |
| Cross-Section Rotation | The clockwise rotation angle of a slanted column (viewed from top to base). This angle can be carried out to 3 decimal places. Negative numbers rotate counterclockwise. If a slanted column is in a vertical state, then this rotation is measured from Project North. Otherwise, it is measured from the vertical position. |
| Analytical Alignment | |
| Top Alignment Method |
Either Auto-detect or Projection. Specifies if the horizontal and vertical references of the column top are automatically justified or have a defined projection. |
| Top y Projection |
Either Location Line, Left of Element, Center of Element, Right of Element, <Grids...> , or <Reference Planes...>. Available when Top Alignment Method is specified as Projection. Specifies the horizontal location of the analytical model at the top of the column. |
| Top z Projection |
Either Location Line, Top of Element, Center of Element, Bottom of Element, <Level...>, or <Reference Planes...>. Available when Top Alignment Method is specified as Projection. Specifies the vertical location of the analytical model at the top of the column. |
| Top Extension Method |
Either Auto-detect or Projection. Specifies if the vertical extension of the column top is automatically justified or have a defined projection. |
| Top x Projection |
Either Top Level Reference, Top of Column, <Level...>, or <Reference Planes...>. Available when Top Extension Method is specified as Projection. Specifies the vertical extension location of the analytical model at the top of the column. |
| Base Alignment Method |
Either Auto-detect or Projection. Specifies if the horizontal and vertical references of the column base are automatically justified or have a defined projection. |
| Base y Projection |
Either Location Line, Left of Element, Center of Element, Right of Element, <Grids...>, or <Reference Planes...>. Available when Base Alignment Method is specified as Projection. Specifies the horizontal location of the analytical model at the base of the column. |
| Base z Projection |
Either Location Line, Top of Element, Center of Element, Bottom of Element, <Level...>, or <Reference Planes...>. Available when Base Alignment Method is specified as Projection. Specifies the vertical location of the analytical model at the base of the column. |
| Base Extension Method |
Either Auto-detect or Projection. Specifies if the vertical extension of the column base is automatically justified or has a defined projection. |
| Base x Projection |
Either Base Level Reference, Bottom of Column, <Level...>, or <Reference Planes...>. Available when Base Extension Method is specified as Projection. Specifies the vertical extension location of the analytical model at the base of the column. |
| Releases/Member Forces | |
| Top Release | Specifies the end release condition: either Fixed, Pinned, Bending Moment or User Defined. User Defined allows you to enable/disable each of the end release conditions. |
| Top Fx | Translational release at the top end of the column along the x-axis. When selected the degree of freedom is released and the force is not available. |
| Top Fy | Translational release at the top end of the column along the y-axis. When selected the degree of freedom is released and the force is not available. |
| Top Fz | Translational release at the top end of the column along the z-axis. When selected the degree of freedom is released and the force is not available. |
| Top Mx | Rotational release at the top end of the column along the x-axis. When selected the degree of freedom is released and the moment is not available. |
| Top My | Rotational release at the top end of the column along the y-axis. When selected the degree of freedom is released and the moment is not available. |
| Top Mz | Rotational release at the top end of the column along the z-axis. When selected the degree of freedom is released and the moment is not available. |
| Base Release | Specifies the end release condition: either Fixed, Pinned, Bending Moment or User Defined. User Defined allows you to enable/disable each of the end release conditions. |
| Base Fx | Translational release at the base of the column along the x-axis. When selected the degree of freedom is released and the force is not available. |
| Base Fy | Translational release at the base of the column along the y-axis. When selected the degree of freedom is released and the force is not available. |
| Base Fz | Translational release at the base of the column along the z-axis. When selected the degree of freedom is released and the force is not available. |
| Base Mx | Rotational release at the base of the column along the x-axis. When selected the degree of freedom is released and the moment is not available. |
| Base My | Rotational release at the base of the column along the y-axis. When selected the degree of freedom is released and the moment is not available. |
| Base Mz | Rotational release at the base of the column along the z-axis. When selected the degree of freedom is released and the moment is not available. |
| Member Forces | Specifies the internal forces at the top and base of the analytical column. This data communicates load information for both documentation and connection fabrication. Click Edit to enter user-defined force and moment values. |
| Identity Data | |
| Member Number | An identifier created for the analytical member. This value should be unique across Analytical Beams, Analytical Braces and Analytical Columns in a project. Revit warns you if the number is already used but allows you to continue using it. You can see the warning using the Review Warnings tool. See Reviewing Warning Messages. |

| Phasing | |
| Phase Created | Indicates in which phase the column was created. See Project Phasing |
| Phase Demolished | Indicates in which phase the column was demolished. See Project Phasing |
