Seismic Analysis of Intz Tank with Change in Seismic Zones

A 10 lac liters of Intz type water tank is considered for this thesis work. The structural size was decided on the basis of the various literates studied and considering practical site considerations. For this purpose, types of loads and their intensities were considered as per the particular Indian code such as IS 875 part-01 and 02 for dead load and live load and IS 1893 part 01 for seismic loading on water tank. As these loading and loading combinations undergoes a tedious manual calculations structural design software Staad Pro. will be used for analysis and design. After detailed analysis it is found that Change in seismic severity has significant effect on the beam reaction in horizontal X direction with no change in horizontal Z-direction. Changes in seismic severity does not affect the moment values of structure from zone II to Zone III but a slight change was observed between the values of Zone III and Zone IV in Horizontal X and Z direction. An Increase of 261.53 % in the intensity of absolute pressure was observed as the severity changes from low to high, thus reflecting the significance of seismic severity.
