Lift or Across-Wind Response to Tapered Stacks

摘要: In the present study, structure of shedding forces from a slender tapered was studied in considerable detail both smooth uniform flow and turbulent shear flow. From this study simplified description is developed successfully employed to predict response an aeroelastic model. A significant finding that maximum fundamental mode occurs when frequency at about one third stack height equal natural frequency. The observations made during are develop equation might be used behavior full-scale structures. significance loads due vortex structures examined. For typical concrete it deduced drag likely dominant with regard stresses over lower 2/3 while excitation second consideration for upper or thereabouts.
