The transmission infrastructure in the U.S. faces substantial risk from hurricanes. Wind-induced damage poses an immense threat to the electric power grid; such hazards have significantly impacted the supply, generation, and delivery of power to large portions of the U.S. in the past. When exposed to strong winds, critical demands in several elements in transmission tower-line systems may exceed corresponding capacities and trigger various modes of failure. Enhancing the resilience of the transmission grid against increasing threats from hurricanes and strong winds is therefore of critical importance. The results of 1:50 aeroelastic scaled models of a self-supported steel lattice tower …
