Abstract:

Elevated water storage tanks are the lifeline structures in urban areas that should remain serviceable during and after a seismic event. Experience learned from the past earthquakes worldwide showed that elevated water tanks were heavily damaged or collapsed during a seismic event. This failure attributes to the deficiency and misjudgment in the analysis and design aspects. Design procedures available in the present seismic codes indirectly address the inelastic behavior, and they showed the overestimates of the actual strength. Proper selection of a staging system and engineering demand parameters are the key elements of the elevated water reservoir design. In the present work, we performed a non-linear time history analysis on the models prepared about the data of existing elevated water tanks available within the Nanded region (Maharashtra-India). The obtained engineering demand parameters were used to predict the efficacy of elevated water tanks.
