Hi All
I am trying to add a custom connection between a beam and a plate. The plate has positive and negative interfaces. The beam shares both of its nodes with the plate (coplanar with the plate). I intersected the elements to make sure that the beam nodes lie on the edges of the plate. After i add the connection and mesh, I get this error when attempting to run the model: "connected and reference object share an uninterfaced node plaxis". I reviewed the tutorial video on this subject: Custom Connections - GeoStudio | PLAXIS Wiki - GeoStudio | PLAXIS - Bentley Communities, and the same error was reported when the beam shares one node with the edge of the plate element, and the solution was simply to add another interface. I already have both interfaces, and the difference is that the beam shares both of its nodes with the plate (rather than one node).
Can someone help with this?
Thank you!
Hi Omar,
The “invalid connections” warning messages are most likely related to the beam-plate custom connection. The idea of a beam-plate connection is that the end node of a beam is connected to (one point of) the plate, following the example illustrated in the following link:
https://communities.bentley.com/products/geotech-analysis/w/plaxis-soilvision-wiki/45878/custom-connections
In your case, the plate and beam share multiple connection points. Since it is possible to create interfaces only for plate elements but not for line elements, the error message warns you that the connections share an uninterfaced node.
I don’t know what kind of connection you are aiming for. Still, as a potential workaround, you can create custom connections between adjacent plate elements (plate-to-plate connections) and define them accordingly. However, please remember that you still have to create interfaces on both sides of the plates.
