concrete column fixity
concrete column fixity
(OP)
In conventional two way slab construction the columns are poured first with the reinforcement extending above the slab. When the slab is poured do you consider the coonection as fixed or pinned? I have always designed the column for the unbalanced moment and axial load. A recent discussion with a more senior engineer, he treats the column as pinned. Do most engineers consider the connection pinned or fixed (or somewhere between)?

....but now that I've said that, there may be implications with the column to slab connection - specifically the shear calculations over the column (slab to column punching shear) that takes moment into account in determining the shear stress in the slab directly surrounding the column.
