Connections between structural nodes could be of three types:
- Rigid connection: defined by specifying two parts at segment points, for example between a pier and a main girder
- Spring: a connection between two nodes that is geometrically defined by two different connection points that can have different cross-sections from different elements.
- Spring-0: a spring connection to any node 0 (as Earth or full model external rigid support)
An additional option is available as a fast input tool:
- Abutment: creates the three separate spring support systems where the middle is connected to node 0, and the Left and Right are connected to a part as a beam node.
These connections allow the user to create the necessary supports in the structural model segment points using rigidity constants.
