Type of Element to use for Column compression only restraint

Type of Element to use for Column compression only restraint

Type of Element to use for Column compression only restraint

(OP)
Hello,

I would like to ask for advice/how-to on what type of element to use for a column restraint. I have a column (frame element) that is simply bearing on a "rigid" ground and so the column is restricted only in the direction where it will compress the ground. I would like the column to be able to be able to lift, and be able to translate in the lateral directions. I'm assuming I would use a link/spring however I am getting tensional forces whenever i run the analysis.

Thanks in advance

Hi

I think you better use Gap/Link Element and if you don't want to consider soil flexibility you should use a very large magnitude for stiffness to gain good results.
