IS 11504 : 2020 Criteria for Structural Design of Reinforced Concrete Natural Draught Cooling Towers

Revised Standard from Last Update.

1 SCOPE

1.1 This standard essentially deals with the safety concepts, structural design and construction considerations of cast in-situ reinforced concrete hyperbolic natural draught cooling tower shells. Provisions of this standard may be applied to all common cooling tower shapes formed by conic sections.

1.2 The requirements of number, size, structural layout, location and spacing of towers arising out of thermal design considerations are not covered in this standard.

1.3 This standard also does not deal with the packing material, types, water distribution system and the method of testing the performance requirements of cooling towers.

1.4 Provisions of IS 2210 and IS 2204 shall also apply to the design and construction of cooling tower shells wherever they are not covered in this standard.
