As an adjunct to IS 1893, IS 4326 'Code of practice for earthquake resistant design and construction of buildings' was prepared in 1967 and subsequently revised in 1976 to be in line with IS 1893 : 1975. Since 1984 revision of IS 1893 was minor, it did not require a revision of IS 4326.

1) The procedure suggested in IS: 1893-1984 considers the tank as single degree of freedom system (lumped mass model) which is applicable to closed tanks completely full of water.

It is to serve this purpose that IS 1893 : 1962 'Recommendations for earthquake resistant design of structures' was published and revised first time in 1966. ... Clauses on concrete and masonry dams were modified, taking into account their dynamic behavionr during earthquakes.

For seismic zone V, the zone factor Z is 0.36 (Table 2 of IS: 1893). Being an office building, the importance factor, I, is 1.0 (Table 6 of IS: 1893). Building is required to be provided with moment resisting frames detailed as per IS: 13920-1993. Hence, the response reduction factor, R, is 5.
