Picked-up columns are supported on beams at their lowest point.

In order to draw a picked-up column, you will need to create point objects at required location on the relevant beams, and connect the two points (one located on the lower level beam and the second on the next upper level beam) with a line element (defined as a column member).

Application of loads, and analysis & design is similar to the other normal columns of a frame structure.

i did. etabs designing it as a column but not designing the lower beam for this pick up column load.

In case you have subdivided the beam (that is supporting the lowest picked-up column) correctly for creating the support point of picked-up column, it is unlikely that you don't get the beam design or reinforcement. It appears that you might have missed something or made some mistake in your model.

See the attached image (taken from an ETABS 9 model, I have created to cross-check the results) and note the reinforcement of the left side beam (supporting the picked-up columns), as well as for the supported columns at all levels.

can we consider loads on pick up column given by etabs then apply it as point load to design beam which is supporting pick up col?

Why do you want to do this?

yes you can assign load of pick up to beam.

because it is a easier way to get maximum deflections, moments and shear on the beam having pick up column.
