Modeling technique to connect 2D element to 1D element

Hi everyone,
What is better approach to connect a 2D shell element to a 1D element? I have a assembly with 3 components, 1 bracket modeled by 2D elements which carries the load, 1 plate modeled by 2D elements likewise, where the bracket is lay and also, shall be interface component between bracket and beam component and 1 beam component modeled by 1D elements where loads and displacements must be transfered. The connection between bracket and plate was modeled by Cbush elements which represents bolts stiffness, therefore, my concern is how can I model the connection between plate and beam to represent a weld?

I have attached a picture which it clarifies my problem. The green one is a bracket, red is a plate and magenta is a beam.

Thank you,

Richard

    Hi Richard,

    For the beam you have selected thinwalled box as standard section type. Can you confirm whether you want the same section?.

    Hi George,

    Yes, I use a thinwalled box as section for 1D beam.

    Hello @rscaetan

     

    Did you think about area connectors (with element type as rigid for example)?

     

    Please check area connectors between the nodes of beam elements and nodes of plates.

    To be honest, I really don't know how to use area connector.

    Hi,

    Connect the beam and the shell component with rigid elements.
