Requires: IES VAConnect
Requires: Advanced Level
VAConnect consists of two stand-alone utilities for connection design, currently just steel connections per AISC. These programs can be launched from within VisualAnalysis. Integration with VAConnect can save a tremendous amount of time because it exports forces from many load cases and multiple joints, saving you all the bookkeeping. In VAConnect, there is a steel base plate component with anchorage calculations, and a beam-to-column shear-tab component.
How to Use IES VAConnect
- Turn on the Auto-Connections option in the Project settings. You may customize these.
- Define Result Type in project settings: VAConnect can use service case results or "pre-factored" results.
- Go to Load Case Manager and turn on the analysis for all necessary load cases (they may not be enabled for service cases).
- Use the Filter the Design View you show connection icons, click on the connection to view properties and access VAConnect.
Connection Shapes & Geometry Limitations
General Requirements
- Steel materials and shapes only
- Grouped connections must be 'identical' in type, shape, orientations, etc.
- Only LRFD load combinations are supported
Base Plate Requirements
- Base plate is assumed to be perpendicular to the member's local axis
- A single member framing into a supported node or with spring-supports (no braces may frame into this node!)
- Permitted shapes: I-Beams, HSS (rectangular tubes), Pipe, Rectangle, or Round
- Will not design plates for biaxial bending.
Shear Tab Requirements
- Beam is nearly perpendicular to column or girder with end-released connection (~15° tolerance)
- A single member framing into a support column or girder
- Permitted beam shapes: I-Beams, Channels
- Permitted supporting member shapes: I-Beams, Channels, HSS, Pipe, Rectangle or Round
Notes:
- The preferred approach is to export service-case results. While you may export “factored” results into VAConnect, which would go in as “prefactored” loads. This is not the best way to design a connection. Use the type in .
- The coordinate systems are different between VisualAnalysis and VAConnect.
- Member local forces in VisualAnalysis are exported to VAConnect, transformed into the appropriate directions.
- Once the project is created in VAConnect it is not “updated” from VisualAnalysis, and no information transfers back to VisualAnalysis.
- If your forces change in VisualAnalysis you must start the process over or manually update the VAConnect project.
- VAConnect reports are only available in VisualAnalysis 'per session'. If you exit and restart VisualAnalysis any VAConnect reports are no longer present.
- No connection data input into VAConnect is currently stored or transferred back to VisualAnalysis.
- You may save VAConnect project files manually to store your input-data and settings for each connection design.
Troubleshooting
If you have problems launching VAConnect from within VisualAnalysis, check the following:
- Uninstall any older versions of VAConnect (2.0 or 1.0) and VisualAnalysis (prior to 12.0), from Control Panel
- Check the "File Associations" on one of the example Base Plate and/or Shear Tab projects that ship with VAConnect
- Re-install the latest versions of VisualAnalysis and then VAConnect
