Quasi-static versus dynamic space wind response of slender structures

Field measurement and aeroelastic wind tunnel test of wind‐induced vibrations of lattice tower

“…Moreover, lattice towers are hollow structures, and the wind-induced dynamic vibrations of them in the along-wind, across-wind, and torsional directions are very complicated. [1,2] Although methods to calculate the responses of lattice towers to along-wind loads have been extensively explored, [3][4][5][6][7] few studies have been conducted to examine their responses to across-wind loads under strong winds.The major methods to study wind-induced vibrations of lattice towers are evolving based on field measurements and wind tunnel tests. The former are more common because the testing structures and circumstances are both realistic because of which the results are more reliable.Hiramatsu and Akagi [8] conducted a full-scale observation to investigate the response characteristics of lattice steel towers with square sections using angled steel and proposed expressions for response estimation to explain the along-wind and torsional responses of the towers based on the stationary approach.…”
