Design of different Shape of Water Tank by using Indian Code

Different shape of ESR, IS 3370:1965, IS 3370:2009(new version), Limit State Method and Working State Method
Limit state method is widely used at present in comparison to working stress method with the following advantages:
• Materials are treated according to their properties
• Loads are treated according to their nature.
• Structures generally fail when they reach their limit state, not their elastic state.
However, when structures reach to their limit state, the cracking width in the structure may be significantly higher comparative to a structure designed by working stress method at the same stage. IS: 3370 i.e. the Indian Standard specifications for construction of liquid retaining structures did not adopt limit state design method for long. However, IS:3370 has adopted the limit state design method after considering checks over the cracking width Design of ESR of using IS:3370:2009 concrete structures for storage of liquids.
