Lateral Stability Improvement for Elevated Steel Water Storage Reservoir in Severe Wind and Earthquake Zone using Etabs ijtsrd
Elevated water tanks are most commonly used in storing of water to supply at a certain height for pressurizing in the water distribution system for various purposes. A major irregularity is along the height of the structure due to heavy water mass on the top and phenomenon of hydrodynamic interaction between the fluid and the walls of the tanks, hence the effect on the whole structure, with the accelerating in horizontal causing the sloshing effect, which cannot be neglected because of the various research done on the elevated tank, which showed issues which a significant problems in terms of modeling, stability and design of the structure. So, In the present study, the attempts are made to study the behavior of hydrodynamic effect Impact of liquid sloshing in water full and empty condition on elevated steel water storage reservoir in sever wind and earthquakes zone of India. The analysis is done with Equivalent static method, Response spectrum method and also P Delta effect with different combination of lateral and horizontal braced supporting frame systems. For modeling and analysis were performed using Etabs Ultimate 17.0.1 Finite element software. The results of the analysis, in terms of Displacement and Time period, are obtained. For a square tank capacity of 150 m3. Frame with wall supported on cantilever staging and X type diagonal lateral bracing with intermediate horizontal bracing is performed very well and it is most efficient in terms of material used for construction. Saving steel material in horizontal tie beams, Lateral bracing, and intermediate horizontal bracing. Time period decreased for the frame with intermediate horizontal bracing, hence increasing the overall stiffness of the frame and making the frame more stable in terms of displacement.
