Introduction

Figure 1. Configuration of the adhesive connection.

In the component builder approach, the cross-section of a beam is defined by a number of structural components, such as walls and cores. Whereas the wall connectors connect walls along their edges, effectively merging the two walls into a single wall, adhesives connect two structural components, such as walls and cores, as illustrated in fig. 1.

Figure 1 illustrates the role of adhesives. Two structural components, such as walls and cores, denoted ComponentA and ComponentB in fig. 1, are connected along a line. A number of nodes, represented by red circles, are defined along edge A1-A2; similarly, a number of nodes, represented by blue crosses, are defined along edge B1-B2. In general, the number of nodes along the two edges and their locations differ. The adhesive connection establishes constraints between the two sets of nodes through the mortar algorithm.

Notes

  1. Parameter SIDE indicate which side of the structural component is connected to the adhesive.
    • For walls, SIDE = 0 indicates the mold line and SIDE = 1 indicates the opposite side.
    • For cores, Side = 1, 2, 3, 4 refers to the number of the edge of the corresponding face.
  2. It is possible to specify a value for the penalty coefficient, Penalty, in the mortar algorithm as . (Default value: Penalty = 100).
  3. It is possible to attach comments to the definition of the object; these comments have no effect on its definition.
