You can use `*EQUATION` to connect the DOFs. It shouldn’t be necessary to duplicate beams. There’s also a ccx documentation example where distributing coupling constraints are used for this purpose: [Modeling bolt connection with preloaded beam element - #5 by FEAnalyst](https://prepomax.discourse.group/t/modeling-bolt-connection-with-preloaded-beam-element/1412/5)
