A direct method for the stress analysis of the ring beam and shell of a cooling tower
A direct method for the stress analysis of the ring beam and shell of a cooling tower
A method for obtaining directly the stresses in the ring beam and shell of a cooling tower is presented. The stresses assuming a continuous base support are corrected by means of self-equilibrating base loads to give the actual discrete column support. The circumferential variation of the highly discontinuous base loads is represented by Fourier series. A careful study of the nature of the series involved leads to an explicit determination of significant terms and an assessment of accuracy when the series are truncated. The consequent savings in computation are shown to give the method practical viability.
Examples of results for typical cooling towers are presented, together with typical computer times. It is shown that the method has clear advantages over present methods of determining ring beam stresses.

Abstract
A method for obtaining directly the stresses in the ring beam and shell of a cooling tower is presented. The stresses assuming a continuous base support are corrected by means of self-equilibrating base loads to give the actual discrete column support. The circumferential variation of the highly discontinuous base loads is represented by Fourier series. A careful study of the nature of the series involved leads to an explicit determination of significant terms and an assessment of accuracy when the series are truncated. The consequent savings in computation are shown to give the method practical viability.
Examples of results for typical cooling towers are presented, together with typical computer times. It is shown that the method has clear advantages over present methods of determining ring beam stresses.
