cold joint in concrete column

cold joint in concrete column

cold joint in concrete column

(OP)
If there are cold joints in the column (for example from different concrete pours at different times (next day))
and the cold joints are located in a half of column length. what would happen to that region?

RE: cold joint in concrete column

It's not a problem as far as I know. You'd have to transmit any column shear across the cold joint as shear friction but that's rarely much of a problem. The builder should take care that the column remains plumb across the cold joint of course.

I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.

RE: cold joint in concrete column

Even encountered where the ice had not been removed from the top of the column, resulting in a 1/2" cold joint...

thank you all for the answer, i am not a structural engineer. so i ask that question.
as i know in field, generally the cold-joint of concrete columns located in encounters with beams and slabs.

RE: cold joint in concrete column

The main reason for cold joints in columns is poor planning by the contractor. If the joint is clean, perpendicular to the axis of the column, and well compacted, it should be fine. By how do you assure that when the joint is well down inside a column form?
