Title1:Wind-induced response of tall buildings and structures
Time: 13:30-15:00, 24 November 2017, Friday
Venue: Anzhong Building A212
Abstract: This presentation examines the wind-induced vibrations of tall buildings and structures. In particular, the alongwind and the crosswind excitation mechanisms and response processes are discussed. Turbulence buffeting is the dominant excitation mechanism in the alongwind direction. In the crosswind direction, excitations associated with incident turbulence, vortex shedding and motion dependent excitations are the prominent mechanisms causing crosswind response. The potential impact of interference excitations of tall buildings and the beneficial effects and economical perspective of aerodynamic shape modifications are reviewed.
Title2:The role of wind-structure interaction in air ventilation and air pollution dispersion in urban environment
Time: 13:30-15:00, 27 November 2017, Monday
Venue: Anzhong Building A326
Abstract: The recent economic development in Asia is driven by unprecedented growth in industrial and manufacturing activities. The growth in wealth also witnesses a rapid urbanisation and widespread construction of high-density high-rise commercial and residential buildings in major cities around the world. The air pollution generated by these activities are often poorly control and result in a decline of air quality which is exacerbated by vehicular and other undesirable emissions. This presentation examines the role of wind-structure interaction in air ventilation and air pollution dispersion in urban environment. The results of studies of the pedestrian level wind conditions and dispersion of haze fog and communicable disease around buildings are presented and discussed.
Biography :Professor Kenny Kwok is currently a Professor of Engineering at The University of Sydney. He was previously Professor of Engineering at Western Sydney University (2008 to 2017), Professor of Civil Engineering at Hong Kong University of Science and Technology (1998-2008) and Professor of Wind Engineering at The University of Sydney (1999-2002). Kenny is also Professor Emeritus in the Department of Civil and Environmental Engineering at Hong Kong University of Science and Technology since 2008. His research interests include wind engineering, structural dynamics, vibration control, human perception of motion, and environmental fluid mechanics, particularly with respect to the dynamic behaviour of tall buildings and flexible structures in strong winds. His research focuses on fundamental aspects of building aerodynamics and wind-structure-occupant-damper interactions, and their practical applications to real life situations. He has published over 500 articles in journals, book chapters, invited and keynote papers, and conference papers. He is a Life Member of the Australasian Wind Engineering Society and a Fellow of the Hong Kong Institution of Engineers and Institution of Engineers, Australia.
