Abstract:
Based on the comparative study of parameters, DL/T 5339—2006(China), BS 4485-4:1996(British), VGB-R 610Ue:2005(Germany)were selected as the representative codes and the calculation principles and methods of aerostatic stability of hyperboloidal cooling tower structures were surveyed, especially for the differences of parameters for global stability and their influences. Several representative hyperboloidal cooling towers were taken as examples to assess the final distinction in global and local stability. The results show that the global stability factors agree well with each other and the factors from the global and local stability can also be in conformity if DL/T 5339—2006 takes the nominal value at the top of windward meridian as the reference wind pressure for global stability.
