Member assembly connections are similar to frame connections, but define the necessary trimming between member parts and the generation of parts such as base plates, gusset plates, and clip angles. Assembly connections control member features including cutbacks, copes, notches, bolt holes, and slots. Whether or not features are placed depends on the member assembly connection type and the geometry of the connection between the members.

There are several basic assembly connections delivered with the software. You can create your own assembly connections by editing the StructAssemblyConnections.xls workbook, and then bulk loading the workbook. For more information on creating your own assembly connections, see the Structural Reference Data Overview.

For very complex nodal connections, instead of writing a custom assembly connection, you might want to try Trim Members in the Structure task.

The following general assembly connections are delivered with the software:

The base plate assembly connection places a plate at the end of an unsupported member. This assembly connection requires an unsupported frame connection on one member. For example, use this assembly connection to place a base plate at the bottom of a column.

The corner gusset plate assembly connection connects a vertical brace to a beam and column intersection using a gusset plate. This assembly connection requires a frame connection with three members, such as vertical corner brace.

The fitted assembly connection connects two members. This assembly connection requires a frame connection with two members, such as axis, seated, or flush. Examples of this connection include a beam framing into a column or a beam framing into another beam.

The gusset plate assembly connection connects a vertical or horizontal brace to a beam or a vertical brace to a column using a gusset plate. This assembly connection requires a frame connection with two members, such as axis.

The miter assembly connection connects two members that meet at an angle but are co-planar. This assembly connection requires a frame connection with two members, such as axis. In addition, the members must be end connected, have the same cross-section, and have the same type category (both are beams for example).

The splice assembly connection connects two members that are collinear and end connected. This assembly connection requires a frame connection with two members, such as axis.

The general surface assembly connection connects a member end with a nonmember surface such as a slab, a deck, or a hull plate. The member is cut to surface and a base plate is placed on the member end.

End Cut Assembly Connections

The following end cut assembly connections are delivered with the software:

The end cut along assembly connection cuts the end of one member to the sides or bottom of another member along the second member's length.

The end cut bearing plate assembly connection connects the end of a member along the axis of another member. This is typically used to attach the end of a member to the flange of the supporting member. The bearing plate connection works at any angle and provides circular, rectangular, and triangular bearing plates depending on the supported member's shape.

The end cut miter assembly connection connects two members that meet at an angle but are co-planar. This assembly connection required a frame connection with two members, such as axis. In addition, the members must be end connected.

The end cut split assembly connection connects two members that are collinear and end connected. This assembly connection requires a frame connection with two members, such as axis.

The end cut split long box assembly connection is used when the supported and supporting members are perpendicular to each other. The supporting member is cut square to the supported member while an item from the Axis category is placed on the supported member.

The end cut split seam angle assembly connection is used when the supported and supporting members are:

  • member axes are collinear to each other

  • have identical cross-section type and size

  • have identical cardinal point and rotation values

The end cut split short box assembly connection is used when the supported and supporting members are perpendicular to each other. The supported member is cut square to the supporting member while an item from the Axis category is placed on the supporting member.

End Cut Assembly Naming Conventions

Each end cut assembly connection name consists of three parts: [EndCutCase]_[WebCutType]_[FlangeCutType]

where:

  • [EndCutCase]

    • Axis - Supported member is bounded by the axis curve of the supporting member

    • LongBox - End-to-end perpendicular supported member is extended, and an axis end cut is applied to the supporting member

    • ShortBox - End-to-end perpendicular supporting member is extended, and an axis end cut is applied to the supported member

    • Miter - End-to-end non-collinear

    • Split - End-to-end collinear

    • SeamAngle - End-to-end collinear where one end is extended

  • [WebCutType]

    The WebCutType is used to type of web cut that is to be applied at the top of the web and at the bottom of the web. The following combinations are available (W indicates a straight cut, C indicates a Cope cut, and S indicates a Snipe cut):

    • W#W#

    • W#C#

    • W#S#

    • C#C#

    • C#S#

    • C#W#

    • S#S#

    • S#C#

    • S#W#

  • [FlangeCutType]

    The FlangeCutType is used to type of flange cut that is to be applied at the left flange section and at the right flange section. The following combinations are available (W indicates a straight cut, C indicates a cope cut, and S indicates a snipe cut):

    • W#W#

    • W#S#

    • S#S#

    • S#W#

You cannot apply different flange cuts when the supported member has both a top flange and a bottom flange. In these cases, the same flange cut type is applied to both the top and bottom flange.

You cannot apply different web cuts or flange cuts in the end-to-end cases. The end-to-end cases place a web cut and flange cut on both the supported member and the supporting member. For these cases, the same web cut and flange cut are applied to both the supported member and the supporting member.

1 - Top left flange
2 - Top right flange
3 - Web top
4 - Web bottom
5 - Bottom right flange
6 - Bottom left flange

Locating Assembly Connections

Assembly connections do not display in the model. However, if you set the Locate Filter to Member Assembly Connections in the Structure task, you can locate and select assembly connections for review and editing. Assembly connections are located at the ends of member parts and appear as circles when you move the cursor over them. Any assembly components, such as gusset plates, associated with the assembly connection also highlight.

When you select an assembly connection, the software displays the assembly connection type in the ribbon. Select the Edit > Properties command to edit the assembly connection properties. You cannot measure distances using the assembly connection graphic as an end point when using the Tools > Measure command.
