It supports the beams and slabs and transfers the loads to the foundations . Hence they have to be designed and detailed adequately to resist both gravity and lateral loads . In some buildings especially when quality control is poor the upper part of column pours from concrete compressive strength of beam or slab UR - http://172.23.153.220/th.pdf ER -
