ABSTRACT

Overhead water tank is a water storage facility supported by a tower and constructed at an elevation to provide useful storage and pressure for a water distribution system. Safety as well as working of such structures is considered as very crucial during earthquakes, since they put up for necessities like drinking water, firefighting during fire accidents. This seismic analysis of overhead water tank structure cannot be carried out on the basis of maximum value of ground acceleration because of nonavailability of ground acceleration data at every location. Hence for seismic analysis of overhead water tank, earthquake response spectrum analysis is widely used.

                  While using this method, smooth design spectra is used to determine the value of displacement and forces in members at every mode of vibration. Hence for seismic analysis of overhead water tank, earthquake response spectrum analysis is widely used. While using this method, smooth design spectra is used to determine the value of bracing are used to analyze the structure under all seismic zones. Also observed the behavior of tank for cyclonic region where wind load is increased by 30%. Analyzed the overhead water tanks of same capacity for different bottom dome deviation angles and concluded. The commercial software STAAD.PRO is used for structural analysis.
