Hi, can anyone please tell me what is the difference if i design a pad footing as fixed and pinned?Which one is better?thanks

RE: Fixed and pinned
We are all a bit conservative about this, but the amount of savings by fixing the base of concrete building columns is relatively small compared to the cost of the structure with pinned bases. For steel, I would be concerned about fixing a base to a foundation element that could settle and induce unwanted bending.
RE: Fixed and pinned
A steel column may be considered pinned to the foundation, but in the case of concrete columns, it is usual to connect rigidly to the foundation. The rotational restraint of the footing then becomes a function of the soil properties.
Please explain what is meant by the question in this thread.

RE: Fixed and pinned
The fixity is between the column and footing only. If the column is fixed to the footing, it transfers axial load and moment to the footing (along with any horizontal shear). If the column is pinned at the footing(which is normally done in steel columns)the footing will be subjected to only axial force and horizontal shear only.
