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

展示了承受模拟飓风风的自支撑钢格架塔的 1:50 比例气动弹性模型的结果。所考虑的格子塔是一种典型结构，用作输电基础设施的塔-绝缘体-导体系统的一部分。气动弹性测试在佛罗里达国际大学 (FIU) 的 NSF 风墙实验设施 (WOW EF) 进行。该塔在 50 m/s 到 92 m/s（等效全尺寸速度）的各种风速下针对不同的风向进行了测试。两种系统识别 (SID) 技术被用来评估顺风气动阻尼并与理论估计值进行比较。SID 技术也被用来评估侧风空气动力学阻尼。进行抖振分析以估计塔的响应并将其与 WOW 的测量值进行比较。根据测量的响应计算阻力和力矩系数，并计算动态放大系数 (DAF) 以及阵风效应系数。分析需要考虑抖振分析方程中湍流强度沿塔高的变化。显示阻力系数与当前标准中提出的值一致。但是，可能需要在格子塔设计中引入基矩系数。共振贡献显示达到塔的峰值响应的 18% 的最大值。并且计算了动态放大系数（DAF）以及阵风效应系数。分析需要考虑抖振分析方程中湍流强度沿塔高的变化。显示阻力系数与当前标准中提出的值一致。但是，可能需要在格子塔设计中引入基矩系数。共振贡献显示达到塔的峰值响应的 18% 的最大值。并且计算了动态放大系数（DAF）以及阵风效应系数。分析需要考虑抖振分析方程中湍流强度沿塔高的变化。显示阻力系数与当前标准中提出的值一致。但是，可能需要在格子塔设计中引入基矩系数。共振贡献显示达到塔的峰值响应的 18% 的最大值。可能需要在格子塔设计中引入基矩系数。共振贡献显示达到塔的峰值响应的 18% 的最大值。在格子塔设计中可能需要引入基矩系数。共振贡献显示达到塔的峰值响应的 18% 的最大值。
