Case Study of Seismic Effect on Hyperbolic Cooling Towers

Sachin Kulkarni, A.V. Kulkarni


This paper deals with the study of seismic analysis of hyperbolic cooling towers. Two existing cooling towers are chosen from Bellary thermal power station (BTPS) as case study. FEA based ANSYS Software is used for the analysis. The boundary conditions considered are Top end free and Bottom end fixed. The material properties of the cooling tower are young’s modulus 31GPa, Poisson’s Ratio 0.15 and density of RCC 25 kN/m3. The analysis is carried out using 8 noded SHELL 93 element. Maximum deflection, Maximum Principal Stress & Strain, Maximum Von Mises Stress, Strains are obtained. The variation in max principal stress v/s thickness, maximum deflection v/s thickness is plotted graphically.

Keywords: Cooling tower, Stress, Strain, SHELL
