Aeroelastic modeling to study the wind-induced response of a self-supported lattice tower

The results from a 1:50 scale aeroelastic model of self-supported steel lattice tower subjected to simulated hurricane winds are presented. considered is typical structure that used as part tower-insulator-conductor system for electrical transmission infrastructure. tests were conducted at the NSF Wall Wind Experimental Facility (WOW EF) Florida International University (FIU). was tested various wind speeds ranging 50 m/s 92 (equivalent full-scale speeds) varying directions. Two identification (SID) techniques utilized evaluate along-wind aerodynamic damping and compare with theoretical estimates. SID also crosswind damping. A buffeting analysis estimate response it measured values WOW. Drag moment coefficients calculated responses, dynamic amplification factors (DAF) well gust effect computed. required consideration variation turbulence intensity along height in analytical equations. drag shown agree proposed current standards. However, there might be need introduce base design. resonance contribution reach maximum 18% peak tower.
