Abstract: Stresses due to the individual effects of forces, moments and deformations at the base of a hyperboloidal cooling tower are presented. With the assumption that the column-spacing is sufficiently small to permit taking an average stiffness per unit length, forces and moments in a loaded cooling tower, supported on columns, are calculated for different column stiffnesses and different load distributions in the circumferential direction. It is shown that: all base displacements have finite values, membrane (not bending) stiffness of the column is important and column effect is noticeable when bending noments are significant.
