Determination and Comparison of Wind Loads for Industrial Reinforced Concrete Chimneys

Abstract

Like all other tall structures, determination of wind loads is important for industrial reinforced concrete chimneys. All countries use different wind load standards. These different wind load standards are compared with each other in some studies. For example, in one study by Zhou et al., major international codes and standards for tall buildings were compared. In the first part of this study, modelling information about 10 selected industrial reinforced concrete chimneys is given. All structural and material information about the chimneys are given in the first section. In addition, the first mode natural periods of model chimneys are given. In the second part of this study, procedures of standards used for calculating wind loads are introduced. These standards are ACI 307/98, CICIND 2001, DIN 1056, Eurocode 1 and TS 498. In the third part of the study, the calculated wind loads according to these five standards are shown and compared with each other. In the last part of the study, a conclusion and discussion part is taking place. Copyright © 2010 John Wiley & Sons, Ltd.
