COMPARISON AND DESIGN OF WATER TANK REST ON GROUND BY LSM AND WSM – A REVIEW

Abstract

In the new version of the IS 3370-2009 Code of Practice for concrete structures for the storage of liquids that has adopted the widely used limit state method. According to the provisions of the previous version of the Code (IS 3370-1965), design of water tanks is only allowed by the work effort method. The study was conducted to compare the design provisions of IS 3370 (1965) and IS 3370 (2009). In this study, a comparison of water design reservoirs using Stress Limiting Worker methods is performed. In order to carry out the comparative design of the study, the three types of water tanks set up a circular reservoir with a capacity of 500 kl, an elevated square reservoir of the tank with a capacity of 250 kl and a rectangle of groundwater 250 kl of its capacity. The quantities of materials were calculated for each problem. The results are presented as graphs and tables and noted that the state water tank design method is more economical since the amount of material required is less compared to the work effort method.
