Because of the growing vulnerability of coastal regions to tropical cyclone (TC), or typhoon and hurricane, hazards under climate variability, a thorough knowledge of TC wind characteristics and wind effects on high-rise buildings is highly desired for efficient TC risk mitigation in coastal cities. This paper presents a city-scale typhoon hazard assessment and field monitoring study of wind effects on skyscrapers in a coastal metropolis (Shenzhen, China) during the record-breaking Super Typhoon Mangkhut. Spatiotemporal variation of wind fields over the metropolis was investigated using synchronous wind observations from a network of weather stations and a 356-m-high meteorological tower. Typhoon hazard in the coastal city was assessed through the typhoon hazard map obtained by numerical simulations and validated by wind observations. Wind-induced vibrations and time-varying structural dynamic properties of two representative skyscrapers with heights of 600 and 392 m in Shenzhen were analyzed to determine the dynamic performance and serviceability of the monitored high-rise buildings under violent wind excitations. This integrated city-scale field monitoring and numerical study furthers the understanding of TC wind characteristics in the urban environment, and facilitates the wind-resistant design of future skyscrapers in TC-prone regions.
