Bottom Line: The wind characteristics were analyzed using the measured wind data including the wind speed and wind direction time histories.Besides, the structural response measurements of the monitored building were utilized for modal identification using the Bayesian spectral density approach.Detailed analysis of the field data and the typhoon generated effects on the structural performance are discussed.

ABSTRACT
The goal of this study is to investigate the structural performance of reinforced concrete building under the influence of severe typhoon. For this purpose, full-scale monitoring of a 22-story reinforced concrete building was conducted during the entire passage process of a severe typhoon "Vicente." Vicente was the eighth tropical storm developed in the Western North Pacific Ocean and the South China Sea in 2012. Moreover, it was the strongest and most devastating typhoon that struck Macao since 1999. The overall duration of the typhoon affected period that lasted more than 70 hours and the typhoon eye region covered Macao for around one hour. The wind and structural response measurements were acquired throughout the entire typhoon affected period. The wind characteristics were analyzed using the measured wind data including the wind speed and wind direction time histories. Besides, the structural response measurements of the monitored building were utilized for modal identification using the Bayesian spectral density approach. Detailed analysis of the field data and the typhoon generated effects on the structural performance are discussed.

Mentions: Typhoon Vicente developed as a tropical depression in the Northeast of Manila over the Western North Pacific Ocean on 20 July 2012. On the next day, it entered the South China Sea and the Standby Tropical Cyclone Signal Number 1 was announced in Macao by the Meteorological and Geophysical Bureau. On 22 July, Vicente stalled over the Northeastern region of the South China Sea and it was upgraded to a tropical storm. On 23 July, it began to edge towards the West of Pearl River Estuary of the South China coast. As the sustained wind speed became higher than 41 km/hr, the Signal Number 3 was released at 06:30. Vicente strengthened rapidly and attained to a severe typhoon. Along with the increasing wind speed, the Signal Number 8 was hoisted at 19:00 on the same day. At 02:15 on 24 July, the Signal Number 9 was issued due to the strength of the gale gust and storm force wind. Vicente passed through Macao from the South-Southwest with the shortest core distance of 40 km and its maximum near-center 10-minute sustained wind reached 150 km/hr. Afterwards, Vicente gradually moved away and made a landfall near the Taishan city in the Guangdong province. The signal number was subsequently downgraded to Number 8 and Number 3 at 05:00 and 09:30, respectively. The local wind was weakened during the dissipation of Vicente. Afterwards, all tropical cyclone signals were cancelled at 16:20. The typhoon track and the announced tropical cyclone signals of Vicente are summarized in Figure 3 and Table 1, respectively. From 18:00 on 21 July to 16:20 on 24 July, different tropical cyclone signals were hoisted due to the relevant typhoon generated wind situations. Full-scale monitoring was conducted for 70 hours and 20 minutes to cover the entire tropical cyclone signal hoisting period.
