Aerodynamic Parameters on a Multisided Cylinder for Fatigue Design

Wind-Induced Vibration Monitoring of High-Mast Illumination Poles Using Wireless Smart Sensors

“…This is commonly observed in slender structures with low frequencies [ 27 ]. The structural response due to buffeting is directly proportional to the wind intensity and tends to be higher at higher wind speeds [ 8 , 27 ]. The first mode usually dominates buffeting-induced vibration, while other modes can also contribute to its vibration response [ 4 , 5 , 9 ].…”

“…Typically, structures are not designed to withstand dynamic loads due to crosswind and torsional buffeting, as designs are limited to static analysis according to the maximum crosswind and torsion loads and unit dynamic coefficient [ 6 ]. Slender structures exhibiting low natural frequencies, e.g., less than 1 Hz, rough surface, odd aerodynamic shape, and low damping, are susceptible to buffeting-induced vibration [ 7 , 8 ]. Such vibration becomes significant under high mean wind speed and high-intensity turbulence [ 7 , 8 ].…”

Such vibration becomes significant under high mean wind speed and high-intensity turbulence [ 7 , 8 ]. Galloping-induced vibration is featured by unstable aerodynamic vibration with large amplitude, usually occurring in the crosswind direction [ 5 ].…”
