Analytically modelling along-wind buffeting response of a slender column

Abstract

Slender vertical structures such as tall buildings, antenna
masts, and towers are very sensitive to wind actions that
give rise to large dynamic response. Due to the complex
nature of wind turbulence, it is complicated to model
analytically the wind-induced responses of slender
structures. Current wind codes provide different models
to evaluate dynamic responses but are limited to basic
assumptions. This paper presents a general formulation
to evaluate the buffeting displacement of slender vertical
structures in the along-wind direction, considering the
effects of different turbulent components. An application
for a real structure will illustrate the theory and point
out the limitation of conventional approaches.
