Integration Error Messages

If you try to send a connection to RISAConnection from RISAFloor or RISA-3D, the program will test whether that is a valid connection. If the program finds the connection or the Connection Rules to be incorrect or unsupported, then the program will not design the connection and will give the error in the Connection Results spreadsheet - Limit State column.

The possible error messages are:

Integration Error Messages

Error Message

Cause(s)

Connection not supported

This message occurs when there is a connection configuration that RISAConnection can not design. An example would be a horizontal brace connection where brace members frame into a beam web.

Invalid or missing supporting connection members

This message occurs if the member(s) that a member is framing into is not of the proper material, shape, member type, etc. Also check that the Member Function is the same (lateral or gravity) for all members for a particular connection.

Invalid connection member material

This message occurs if the member's material is not hot-rolled steel.

Invalid connection member shape

This message occurs if the member's shape is not one of the supported shape types for that connection type.

Invalid member/beam slope (more than 15 degrees)

This message occurs if the member being connected has an invalid slope. Currently, beam/column connection design is only for orthogonal connections. If the angle between members is greater than 15 degrees from orthogonal, then this message appears.

Invalid member/brace rotation (more than 15 degrees)

This message occurs if the member being connected has an invalid rotation. Currently, members can only be designed at certain orientations. For example; weak axis beam to column design is not currently supported, so this message appears.

Invalid member skew (more than 15 degrees)

This message occurs if the member being connected has an invalid skew. Currently, beam/column connection design is only for orthogonal connections. If the angle skew between members is greater than 15 degrees from orthogonal, then this message appears.

Connections on skewed members are not supported

This is a similar message to the invalid member skew message.

Invalid vertical brace connection

This message occurs if there was not a valid configuration. If there is not a valid column, beam and vertical brace intersection (at proper orientation, member type, member material, etc) then you may see this message. Note that for integration you must assign BOTH the beam and the brace to the vertical brace Connection Rule.

Brace angle is invalid

For a corner brace or chevron vertical brace connection, the brace angle with the column and beam must be > 10 degrees.

Members have different/missing connection rules

If there is a vertical brace connection and the beam and brace have different Connection Rules, this message appears.

Beam must be a WF in a Chevron brace connection

This message occurs if you have assigned a chevron brace connection type to a tapered WF beam member.

Beam and Column must be WF in Diagonal brace connections

This message will come up if you have assigned a diagonal brace connection type to a tapered WF beam member.

Invalid code. HR Steel and Connection design codes must be the same

This message occurs if the design codes do not match on the Model Settings Codes tab. Seismic design requires that these match.

Invalid design method. IMF/SMF connections must be design with LRFD

This message occurs if an IMF or SMF seismic connection is applied to a model that is assigned the AISC 360-10 (14th edition) ASD design code. Section 1.3 of the AISC 358-10 design code requires that seismic connection design must be done per LRFD.

Incomplete definition of connection rule

This message occurs if you have not selected an appropriate "Beam Conn" or "Col/Girder Conn" input in the Connection Rules spreadsheet. To correct this, simply go back to Connection Rules and select the connection type (Bolted or Welded).

Beam must be drawn continuously over the column

This message occurs when utilizing a Continuous Beam over Column connection type, and the beam framing is set to terminate at the column without spanning the entire width of the column. This error serves as a reminder to ensure that the beam is consistently drawn in a continuous manner over the entire top surface of the column.
