Combined wind and ice loading on antenna towers

Abstract: The present study contains an analysis of the recorded and predicted values of ice accretion for the meteorological stations in Canada; also, the value of the wind pressure associated with the maximum ice accretion is studied. The values were compared with those specified in CAN/CSA S37-M86. Changes to the ice map of Canada are proposed based on the climatic data analyzed, and this map is compared with the one specified in the 1991 edition of the Ontario Highway Bridge Design Code. Also, some modifications to … Show more

“…This is a simplified procedure which recognizes the reduced likelihood of observing maximum wind superposed on maximum ice. Wahba et al (1993) indicate that this ratio covers approximately 85% of all meteorological stations in Canada. However, this is not an issue in the reliability analysis because the variability of wind and ice is considered explicitly through their probability distribution function.…”
