COMPUTATIONAL ANALYSIS AND DESIGN OF CIRCULAR AND RECTANGULAR WATER RETAINING STRUCTURE FOR OPTIMIZATION

Water tanks are water retaining structure, The important criteria of water tank should be such that it should be leak proof, long lasting and economical too. Economics of structure can be achieved through quantity of constituents of materials as concrete, and steel. For Optimization, paper deals with two different types of water tanks (1) Rectangular and (2) Circular. Selected water tanks were considered for the restrained base as a boundary condition. The selected water tanks were analyzed and designed by two well established methods 1, IS code method and 2, analytical method. The selected water tanks were designed for constant volume of 100 cu. m Mix M-30 with Fe – 415 and IS code 3370 part I, II, III, IV along with IS 456:2000 All the water tanks, mentioned above, were designed by working stress method only. A Computer program was developed to obtain an accuracy in results. The results thus obtained were compared and shown in a tabular form. From the observations, it was concluded that the circular water tanks designed by IS code method were economical as compared with all the other types of water tanks. Similarly, it was observed that saving in cost is proportional to decrease of height of water tank.
