Parametric Earthquake Analysis of Natural Draught Hyperbolic Cooling Tower

Hyperbolic cooling tower is a tall and hyperboloidal shaped device having open topped which is used in power plants, nuclear and electrical plants to cool the water. Now-a-days the power plants are the major requirements of society but having a drawback that heat escapes out from the power plants in the form of water can be harmful to the environment. A survey says that only U S industries use approximately 500 billion gallons of water a day, so that hot water can either mix to the water streams or can be recycled. But if water recycled to the environment it can be harmful to the water species, and if the water is recycled to the power plants then it is not possible to convert the hot water into steam, so cooling tower is the right choice to cool the hot water and reuse the water. In this study, cooling tower is analyzed under the effect of earthquake forces using STAAD.Pro software. The parameters considered are top diameter and height of cooling with constant thickness under different earthquake zones of India. Various parameters on the basis of which results are analyzed are maximum von Mises stress, maximum principal stress, maximum shear stress and maximum deflection. Based on these results, salient conclusions are drawn.
