The elevated rectangular water tank generally constructed with monolithic connections between short walls, long walls and base slab. Due to this monolithic connections joints are tends to rotate which modifies the moments in the tank wall. These moments are differ from the moments given by IS code for certain boundary conditions. Present work aims at the finite element analysis of elevated, closed rectangular (i.e. propped at top) partially filled water tanks of R.C.C. construction supported on four corner columns. For the purpose of studies, tanks of various heights i.e. 2.5m and 3m are considered with different aspect ratio of wall ranging from 0.67 to 2.8 and Lz /Lx ratio between 1.33 to 2.0. Thickness of the walls and base slab are assumed. Each wall is discredited into numbers of rectangular four nodded elements with six degrees of freedom per node. Type of load considered is hydrostatic load due to the tank in partially filled condition. After analysis it is found that I.S. Code moments get significantly modified mainly due to rotation of the junction of wall and base slab and also rotation of the vertical edges at junction of short wall and long wall.
