Design of Intze Tank in Perspective of Revision of IS: 3370

Intze type tank is commonly used overhead water tank in India. These tanks are designed as per IS: 3370 i.e. Code of practice for concrete structures for storage of liquids. BIS implemented the revised version of IS 3370 (part 1& 2) after a long time from its 1965 version in year 2009. Presently large number of overhead water tanks is used to distribute the water for public utility. In which most of the water tanks were designed as per old IS Code: 3370–1965 without considering earthquake forces. The objective of this dissertation is to shed light on the difference in the design parameters of (a) intze water tanks without considering earthquake forces (b) intze water tanks designed with earthquake forces. First design is based on Indian standard code: 3370–1965 and second design is based on Indian standard code: 3370–2009 and draft code 1893-Part 2, (2005) considering two mass modal i.e. impulsive and convective mode method. Intze tank supported on frame staging is considered in present study.
