Connection Range (Extend Core to Enable Connection)

For Beams and Columns: This option virtually extends the 1D Member’s core length along its axis.

The purpose of virtually extending the core is to enable the Beam or Column to achieve a core connection with other elements. As a result, Adjustment Rules (which require core connections) can go into effect.

This can be useful with certain prefabricated elements which contain deliberate core gaps at either end (e.g. to make room for insulation or detailing.) This Connection Range virtually extends the core to fill these gaps.

Important Notes:

–This option extends the length of the element core only virtually: it has no effect whatsoever on the physical model element, and does not extend the 1D Member.

–The extra Connection Range is considered when you run a Model Check on the Structural Analytical Model. If the Connection Range enables the structural connection, then the Model Check will consider the elements to be continuous for the purposes of the Structural Analytical Model.

–You can add an extra Connection Range to the element only if the Stretch & Cutback and/or Offset boxes are also checked in Column or Beam Settings.

In Beam or Column Settings:

1.Check the Connection Range option.

2.Enter the length of the extension.

The value must be at least as long than the shortest distance between the element cores to be connected.

In this example, we want to extend the Beam Connection Range must be at least 150.

3.Choose “Start”, “End”, or “Both” to define which end should be extended. The “Both” option adds the extended length at both ends.

Note: To see which end is which, turn on “Show Local Coordinate Systems” to see the element’s direction arrow.

In Adjustment Rules:

The maximum allowed stretch must exceed the distance between the structural axis to be connected. This “Max stretch” value is applied to the either or both ends of the Connection Range.

Thanks to the Beam’s Connection Range setting, the Stretch Adjuster works as desired, and the 1D Members are connected.
