Hello,
My first post on this forum so my apologies if the format is not as required.
I am modelling a number of hollow steel section (HSS) columns in ANSYS Workbench. The columns are in a pinned-pinned configuration and I intend on carrying out non-linear buckling analyses. The only problem I am having is how to properly model the end of the columns. In the experimental campaign I am validating my model from, the ends of the columns were welded to thick end plates for load application and to prevent local buckling of the columns at the ends.
The solution I have adopted right now is to explicitly model the end plates and connect the columns to the plates using MPC bonded contacts. I also assigned a very high elastic modulus to the end plates to ensure they behave as rigid bodies. I was wondering if someone with more experience in ANSYS Workbench could verify if this is the proper modelling practice or if there is an easier way of assigning this boundary condition.
Any help would be greatly appreciated.
