The basic principal of earthquake resistance design of structures is that the structure should not collapse but damage to the structural elements is permitted. Water tank is very valuable structure. Staging type of tanks is generally collapse during earthquake, so it is required to calculate earthquake load properly. Past evidence had shown that the elevated tanks are susceptible. due to earthquake. The tanks are designed based on linear elastic methods which are considered only elastic range. Factor shows the reserved strength of water tank in IS 1893-2016(Part-2) value of R factor for RC elevated shaft supported tank is 2.5 and for column supported 4. One constant R-value for elevated water tank cannot reflect the expected inelastic behavior of all elevated water tanks located in different seismic zone, different soil condition, and having different height. So it is requisite to find out absolute value of R factor for various type of RC elevated tank individually. The present study efforts are made to evaluate the response reduction factor of RC framed staging elevated water tank having varying staging height, capacities, soil condition and zones. The main objective of this study is to verify the R factor of most common designed Elevated Intze tank through comparing the assumed R factor during design to actual R factor obtained from non-linear analysis.
