Typhoon Dolphin struck the eastern coast of China this week, causing significant structural sway in Shanghai and widespread infrastructure damage [1].

The storm's intensity tested the resilience of one of the world's tallest buildings and disrupted transportation across multiple provinces, highlighting the vulnerability of coastal urban centers to extreme weather.

Typhoon Dolphin traveled over 6,000 km across the Pacific before making landfall [1]. In Shanghai, the 632-meter Shanghai Tower experienced noticeable movement due to the extreme winds [1]. To counter this sway, a 1,000-ton vibration-absorbing mass located on the 125th floor moved about 50 cm [1]. This movement remains well within the tower's design limit of two meters [1].

Beyond the skyline, the storm brought devastating conditions to the ground. Maximum wind speeds were reported at over 150 km/h, which toppled trucks and sent temporary buildings tumbling [1], [2]. In Taizhou, Zhejiang province, the winds were strong enough to blow billboards, solar panels, and concrete blocks onto parked cars [1].

One Taizhou resident said a concrete block smashed through a driver's side window, noting that another block hit the rear of the car and damaged a neighboring vehicle [1].

Heavy rain accompanied the wind, leading to severe flooding in several areas. In some locations, water levels rose high enough to reach window frames [1].

Kang Jeong-kyu, a YTN correspondent, said trucks were overturned and temporary buildings were scattered by the winds exceeding 150 km/h [2].

“The 632-meter Shanghai Tower experienced noticeable movement due to the extreme winds.”

The event demonstrates the critical role of tuned mass dampers in modern skyscraper engineering, as the Shanghai Tower's internal systems successfully mitigated wind-induced oscillation. However, the widespread damage to ground-level infrastructure and vehicles in Zhejiang and Shanghai underscores a persistent gap between high-tech structural resilience and the vulnerability of general urban assets during super-typhoons.
