Columns are structural elements in architecture that transmit weight through compression to other elements. They support roofs and upper floors. Columns are constructed through layout, reinforcement with steel bars according to structural drawings, forming, and pouring concrete. The drawings specify each column's size, concrete ratio, steel bars and diameters based on the load and safety factor.

10. • A column is used to support the weight of the
roof and/or the upper floors
• The size, cement concrete ratio and numbers
of steel bars with their diameter are available
in structural drawings which are designed
according to the load born by the column and
factor of safety.
