Parametric Study of R.C Elevated Rectangular Tank for Economical Design Aspect

The tank is considered two degrees of freedom system with a large mass is located at the top, supported by columns or frame supporting system. The behavior of tank under earthquake loading is greatly depending on the height of staging and mass of located at the top of staging. This studying work is shown the effect of container height on seismic behavior of R.C elevated rectangular water tank as well as the comparison of the Indian and USA seismic design codes. The elevated water tank with various container heights such as (3.5m, 3.6m, 3.7m and 3.8m) and same supporting system with four capacities such as (200,300,400, & 500 m3) in IV seismic zone were studied in STAAD.pro and Excel sheet developed program. The spring mass model as per IS 1893:2006 (part) 2 draft code the water mass consisting of the convective and impulsive masses was used for analysis. Parameter of studying such as maximum displacement, maximum base shear and maximum overturning moment for different container height and IV seismic zone. Also compared the base shear value of water tank by using the seismic design code of USA and IS with subjected to IV seismic zone.
