Tool name Description


Section
Opens the Assign section dialog, which is used to assign sections to members. Existing sections in the model can be used or new sections can be added to the model.


Material
Opens the Assign material dialog, which is used to assign materials to members or surfaces. Existing materials in the model can be used or new ones can be added to the model.


Description
Select a member type from the drop-down list to assign to the selected members.
  • Beam Description
  • Column Description
  • Brace Description


Connection Tags
Opens the Add Connection Tags dialog, which is used to define new connection tags and optionally assign member end restraints associated with a connection tag.
Table 2. Edit group
Tool name Description


Rotate >
Reset Rotation

Rotates the section to zero about the longitudinal axis.

Rotate 90°
Rotate the section 90 clockwise about the longitudinal axis.
Rotate 180°
Rotate the section 180 clockwise about the longitudinal axis.
Rotate 270°
Rotate the section 270 clockwise about the longitudinal axis.
Custom Rotation

Opens the Modify member orientation dialog, which is used to specify an arbitrary rotation angle.



Hinge Both Ends

This tool releases both ends of the selected members for bending moments about local axes y and z (My and Mz are free to rotate).



Fix Both Ends

This tool sets all degrees of freedom to fixed in the selected elements.



Hinge End >
Hinge about major principal axis Click to release the bending moment fixity about the major principal axis at the member end nodes currently selected. Both the member and nodes must be selected.
Hinge about minor principal axis Click to release the bending moment fixity about the minor principal axis at the member end nodes currently selected. Both the member and nodes must be selected.
Hinge about torsional axis Click to release the torsional fixity at one end of the currently selected members.


Fix End >
Fix About Local Axis z Click to fix the bending moment about the major principal axis at the member end nodes currently selected. Both the member and nodes must be selected.
Fix About Local Axis y Click to fix the bending moment about the minor principal axis at the member end nodes currently selected. Both the member and nodes must be selected.
Fix Torsional Moment Click to fix torsion of the currently selected members.


Axial Behavior >
Tension-Only Member Click this tool button to indicate that all currently selected members can only carry tension forces.
Compression-Only Member Click this tool button to indicate that all currently selected members can only carry compression forces.
Complete Click this tool to restore full axial capacity in both tension and compression (i.e., the default specification).


Local Axis >
Local Axis y Pointing a Selected Node Click this tool to rotate the member's local y axis to point to a selected node.
Local Axis y Parallel to Two Selected Nodes Click this tool to rotate the member's local y axis parallel to a line between a pair of selected nodes.
Local Axis z Pointing a Selected Node Click this tool to rotate the member's local z axis to point to a selected node.
Local Axis z Parallel to Two Selected Nodes Click this tool to rotate the member's local z axis parallel to a line between a pair of selected nodes.


End Offsets
Opens the Modify Member End Offsets dialog, which is used to rigidly offset a frame member end from a joint to model the offset conditions existing at the ends of frame members.


Axial End Offsets
Used to set the end offsets along the members longitudinal axis to the half-depth of the connecting member.

The program detects the depth of the outstanding face of the supporting member from its own centerline. The program then sets the local x offset equal to this value.



Cross Section Position
Opens the Modify Member Alignment dialog, which is used to align the cross section of the physical member on the analytical member centerline (i.e., member hang points).


Exchange Connectivity
Used to switch the "start" and "end" ends (i.e., Ni and Nj) of the member.
Note: Refer to the Members > Connectivity spreadsheet to review the incidences for members.


Segment Member >
Split members in a number of segments Opens the Segment Member dialog, which is used to split the selected members into divisions of equal length.
Segment member given node and distance Opens the Segment Member from Node dialog, which is used to split the selected members into two at a specified distance from a selected end node.
Segment members at intersections Segments selected members at points where they intersect.


Merge >
Merge members keeping nodes Merges selected members into a single member connecting to the two end nodes. Intermediate nodes will be kept in the model.
Merge members deleting nodes Merges selected members into a single member connecting to the two end nodes. Intermediate nodes will be deleted.
Table 3. Supports group
Tool name Description


Linear Custom Support
Opens the Assign custom support dialog, which is used to assign linear support parameters for the selected member.
Table 4. Loads group
Tool name Description


Concentrated
Opens the Add Member Concentrated Load dialog, which is used to assign concentrated loads in the same direction along a member.


Concentrated Moment
Opens the Add Member Concentrated Moment dialog, which is used to assign concentrated moments in the same direction along a member.


Distributed
Opens the Add member distributed load dialog, which is used to specify a distributed (i.e., linear) load along selected members.


Distributed Moment
Opens the Add Member Distributed Moment dialog, which is used to specify a distributed (i.e., linear) moment along selected members.


Temperature
Opens the Add Temperature Load dialog, which is used to specify a axial or differential temperature across a member that causes a load.


Strain
Opens the Add Strain Load dialog, which is used to specify a known strain in a member, such as one caused by a temperature load.
