Dear Mr. Kadam,

The high yield strength steel produces higher factored shears and they
have to be carried by the beam without exceeding the maximum shear
stress Tcmax given in Table 20 of I.S. 456 : 2000 even though shear
reinforcement is provided. Therefore, higher concrete sections will be
required for beams to resist shears produced during earthquake episode
and it has futhther implications on the stiffness of the frame that
has additional adverse effect on the force distribution and will
attrect higher earthquake forces

This means the proposed steel having high yield strength such as Fe
600 is not welcome and if you look at New Zealand code AS/NZS
4671-2001, they have only Fe 300E and Fe500E category steel.
