Abstract: The dynamic properties of seven supertall buildings that are currently among the world’s 30 tallest are evaluated using field measurements collected during tropical cyclone events. In this study, the natural frequencies ...

Abstract: This paper presents observations of structural dynamic characteristics and wind-induced responses of a 600-m-high skyscraper installed with an active tuned mass damper (ATMD) system during super typhoon Mangkhut. The ...

Abstract: The stochastic subspace algorithm is one of the most widely used structural identification techniques, which is generally involved with the stabilization diagram for estimating modal parameters. However, the conventional ...

Abstract: This paper proposes a novel strategy based on field measurement, wind tunnel tests, and artificial neural network (ANN) for reconstructing the wind pressures on cladding of high-rise buildings and applies it to reconstruct ...

Abstract: The dynamic characteristics of large-scale civil structures are generally evaluated by performing operational modal analysis based on ambient vibration records measured by contact sensors, e.g., accelerometers. However, ...

Abstract: This paper presents the results of observed near-surface winds and wind-induced pressures on the gable roof of an instrumented low-rise building. The observations were made during the strongest typhoon to make landfall in ...

Abstract: This paper investigates the aerodynamic forces on a 600-m-high supertall building based on field measurements during Super Typhoon Mangkhut and wind tunnel test on a 1∶500 scaled model of the monitored building. The local ...

Abstract: This paper develops a horizontal displacement estimation framework for wind-excited high-rise buildings based on limited measurements of accelerations and strains and applies it to reconstruct the displacement responses ...

Abstract: This paper investigates the impact of Super Typhoon Mangkhut on Hong Kong, especially the wind effects on high-rise buildings, based on 24-h-long field measurement records collected from the two tallest skyscrapers (484 ...

Abstract: This paper analyzes the wind pressures on the claddings of a 600-m-high skyscraper in Shenzhen, China, during Super Typhoon Mangkhut on September 16, 2018. A synchronous monitoring system that included 48 pressure transducers ...
