Cooling towers are essential heat rejection structures widely used in power plants and process industries to dissipate excess heat into the atmosphere. Due to their large height and thin shell configuration, cooling towers are highly influenced by thermal, seismic, wind, and other environmental loads. This project focuses on the structural analysis and design of an induced draft circular cooling tower using STAAD Pro software in accordance with relevant Indian Standard codes. A three-dimensional finite element model of the cooling tower is developed by considering dead load, live load, seismic load, and temperature loads. The structural behavior of the cooling tower is analyzed using different construction materials such as reinforced concrete, galvanized steel, stainless steel, and aluminum. Key parameters including shear forces, bending moments, plate stresses, and nodal displacements are evaluated and compared for each material. The comparative study highlights the influence of material properties on the overall structural performance, durability, and service life of the cooling tower. The results indicate that reinforced concrete exhibits superior performance in terms of lower bending moments, reduced shear forces, enhanced corrosion resistance, and improved long-term durability when compared to other materials. This study demonstrates the effectiveness of STAAD Pro in modeling and analyzing complex shell structures such as induced draft cooling towers and provides insights for selecting suitable materials for structural efficiency and economic feasibility.
