Question
The Link defined in the construction stage is not activated.
Answer
In order for boundary conditions to be activated in the construction stage, not only the elements but also the nodes included in the boundary conditions must be activated.
Boundary conditions, such as Elastic Link or Rigid Link, are defined by connecting two or more nodes. Therefore, in order to activate the boundary conditions when defining the construction stage, all connected nodes must be included in the Structure Group assigned to that construction stage.
Let's take the FCM bridge as an example. The PSC box girder and the support located on the bridge deck are connected by Elastic Links.
In this case, if only the PSC box girder and the beam elements of the main span are assigned to the Structure Group and activated in the construction stage CS1, the Elastic Link in the Tree Menu will not be activated because not all nodes included in the Link are activated, even though the boundary condition is included in that construction stage.
When all the nodes included in the Elastic Link are assigned to the Structure Group and the construction stage CS1 is checked, it can be confirmed that the Elastic Link is activated in the Tree Menu.
