Modify the analytical properties of the brace 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 | Used by external analysis applications to determine whether brace conditions contribute to Lateral analysis. |
| Analytical Properties | |
| Family Type | The family type of the element. |
| Physical Material Asset | The name of the physical asset assigned to the brace material (read-only). |
| Length | The length of the analytical model. |
| Cross-Section Rotation | Displays the cross-section rotation of analytical members. The angle of rotation is measured from the work plane of the member and the direction of the center reference plane. |
| Analytical Alignment | |
| Start Alignment Method |
Either Auto-detect or Projection. Specifies if the horizontal and vertical references of the brace start position are automatically justified or have a defined projection. |
| Start y Projection |
Either Location Line, Left of Element, Center of Element, Right of Element, <Grids...>, or <Reference Planes...>. Available when Start Alignment Method is specified as Projection. Specifies the horizontal location of the analytical model at the start of the brace. |
| Start z Projection |
Either Location Line, Top of Element, Center of Element, Bottom of Element, <Level...>, or <Reference Planes...>. Available when Start Alignment Method is specified as Projection. Specifies the vertical location of the analytical model at the start of the brace. |
| End Alignment Method |
Either Auto-detect or Projection. Specifies if the horizontal and vertical references of the brace end position are automatically justified or have a defined projection. |
| End y Projection |
Either Location Line, Left of Element, Center of Element, Right of Element, <Grids...>, or <Reference Planes...>. Available when End Alignment Method is specified as Projection. Specifies the horizontal location of the analytical model at the end of the brace. |
| End z Projection |
Either Location Line, Top of Element, Center of Element, Bottom of Element, <Level...>, or <Reference Planes...>. Available when End Alignment Method is specified as Projection. Specifies the vertical location of the analytical model at the end of the brace. |
| Structural Analysis | |
| Start Release | Specifies the start release condition: either Fixed, Pinned, Bending Moment or User Defined. User Defined allows you to enable/disable each of the start release conditions. |
| Start Fx | The translational release at the start end of the brace along the local x-axis. When selected the degree of freedom is released and the force is not available. |
| Start Fy | The translational release at the start end of the brace along the local y-axis. When selected the degree of freedom is released and the force is not available. |
| Start Fz | The translational release at the start end of the brace along the local z-axis. When selected the degree of freedom is released and the force is not available. |
| Start Mx | The rotational release at the start end of the brace along the local x-axis. When selected the degree of freedom is released and the moment is not available. |
| Start My | The rotational release at the start end of the brace along the local y-axis. When selected the degree of freedom is released and the moment is not available. |
| Start Mz | The rotational release at the start end of the brace along the local z-axis. When selected the degree of freedom is released and the moment is not available. |
| End 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. |
| End Fx | The translational release at the end of the brace along the local x-axis. When selected the degree of freedom is released and the force is not available. |
| End Fy | The translational release at the end of the brace along the local y-axis. When selected the degree of freedom is released and the force is not available. |
| End Fz | The translational release at the end of the brace along the local z-axis. When selected the degree of freedom is released and the force is not available. |
| End Mx | The rotational release at the end of the brace along the local x-axis. When selected the degree of freedom is released and the moment is not available. |
| End My | The rotational release at the end of the brace along the local y-axis. When selected the degree of freedom is released and the moment is not available. |
| End Mz | The rotational release at the end of the brace along the local z-axis. When selected the degree of freedom is released and the moment is not available. |
| Member Forces | Specifies the internal forces at the start and end of the analytical beams and braces. 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. |

| Phase Demolished | Indicates in which phase the brace was demolished. See Project Phasing |
