Why do we use steel in Column?
Why HYSD bar is preferable than plain bar?

Answer Posted / sanatkumar tiwari

As column we know the column is compression member, but due
to lateral pressure there is a tension in column and to
avoid buckling due to axial load and shear crack we are
using steel in column. steel are also used to reduce the
cross sectional area of member.
As we know that HYSD steel is having high strenth than
plain steel, so it reduces the number of bar. therefore it
helps to avoid congestion and increase load carrying
capacity of column.
