Spring Connections

Members can be connected 'spring-like' to nodes.

Spring connection

Types of Springs

Translation springs - Spring in x-direction (axial) - Spring in z-direction (shear force)

Rotation spring - Spring for moment transfer

Setting Spring Stiffness

For each member end you can specify:

  • Translation spring stiffness in x-direction (kN/m)
  • Translation spring stiffness in z-direction (kN/m)
  • Rotation spring stiffness (kNm/rad)

Special Cases

  • Stiffness = 0 - Free (no force transfer)
  • Stiffness = very high - Rigid connection
  • Stiffness = calculated value - Semi-rigid behavior
