Water tanks are the largest utility structures in both public and industrial purposes. This project aims to analyze the response of an intze tank structure subjected to both static and earthquake loads using STAAD Pro software. Intze tanks are commonly used for water storage and distribution in various industries and municipalities. Understanding their structural behavior under different loading conditions is crucial for ensuring their stability and safety. The water tanks are the long life structures. Based on the studies India is the 60% is prone to earthquakes. But many of the structures are designed using the wind force as a lateral load but sometimes the seismic force also leads to collapse of a structure. By the consideration of combination of loads of live load, dead load and wind load or seismic load by using the code of practice IS 875 (part-v). So in this project we manually design a intze tank of 1000000 liters capacity using the codes of IS 456-2000, IS 3370 and will be statically checked using the code of practice of IS 875 part-v and IS 1893 part-II (2016). After the comparison of the manual design, these design parameters will be applied in STAAD Pro software and comparison will be done with manual design and software design.
