Figure 1. Walls Wall A and Wall B are connected with a wall connector.
Figure 2. The location of the points along the connection line are corrected.

In the component builder approach, the cross-section of a beam is defined by a number of structural components, such as walls and cores. Two walls can be connected using wall connectors, effectively merging the two walls into a single wall.

In contrast with adhesives that connect two walls along their mold lines, wall connectors connect walls at their ends, not along the sides defining the mold line. Figure 1 illustrates how two walls, denoted Wall A and Wall B, are connected at their ends: the end of Wall A located at ηA = 1 is connected to Wall B at ηB = 0; a mortar algorithm used to connect the two walls.

If the curves defining Wall A and Wall B do not have a common tangent vector at the connection point, as illustrated in fig. 1, the geometric location of the points in the two walls might not be identical. In such case, the location of the points along the connection line will be corrected automatically to form a common edge.


  1. At the edge along which the two walls are to be connected, the same number of layers, each of identical thicknesses, must be present.
  2. Commands @CONNECTED_AT_0 {WallNameB} and @CONNECTED_AT_1 {WallNameA} imply that the edge at ηB = 0 of WallNameB is connected to the edge at ηA = 1 of WallNameA.
  3. It is possible to specify a value for the penalty coefficient, Penalty, in the mortar algorithm as . (Default value: Penalty = 100).
  4. It is possible to attach comments to the definition of the object; these comments have no effect on its definition.
