Dear Kavi

Pinned or fixed supports are those you use details to provide them. In fact , in ordinary structures we don't have pinned connection. Theoretically, references give a central oriented bent reinforcement detail in RC column or pedestals where the cross point of rods is located on the column (pedestal) and foundation interface. I have seldom seen this detail being applied but it is credible.

In industrial steel structures like bridges or so you can see pinned connection very frequently.

In ordinary steel buildings you can follow other detail than the pedestal I said before. You can provide the bas plate with 2 dowel being aligned in one direction leaving the other direction with a moment free connection. With the base plate you can arrange to have a total pinned connection with the dowel connected in the center of the base plate.
