Speakers: Dr. Songye ZHU(朱松曄), The Hong Kong Polytechnic University



Construction works generate excessive ground-borne vibrations that influence structural safety, human comfort, and equipment functionality. Although vibration criteria that consider structural damage have long been adopted by the construction industry, these criteria are considerably higher than the acceptable vibration limits for ultra-precision equipment and facilities that perform critical societal functions and are often costlier than buildings. Consequently, recent construction projects near structures with vibration-sensitive equipment (such as hospitals and high-tech industrial factories) brings an unprecedented challenge to the construction industry, especially in Hong Kong where new buildings are often constructed with a small separation distance from existing ones because of the shortage of available land. Increasingly stringent vibration limits require not only the prudent selection and execution of construction methods, but also a new perspective and methodology for vibration assessment and control. This presentation introduces the state-of-the-art in the assessment, monitoring and mitigation of construction-induced vibration in several real construction projects relevant to hospitals in Hong Kong. The knowledge gaps, potential solutions, and necessary future research in this field are highlighted for both academics and practitioners.


About Speaker:

Dr. Songye ZHU is an Associate Professor in the Department of Civil and Environmental Engineering at The Hong Kong Polytechnic University. He received his BEng and MSc degrees in Structural Engineering from Tongji University (China) and his Ph.D. degree in Civil Engineering from Lehigh University (USA). He is currently Editor of Advances in Structural Engineering, and President-elect of ASCE (Hong Kong Section). His major research interests include vibration monitoring and mitigation, seismic response reduction, structural health monitoring, and smart materials and structures. He has published over 130 technical papers in these research fields, including 55 peer-reviewed journal papers. He has been awarded the First Prize of Elsevier’s Engineering Audioslides Challenge in 2013, Takuji Kobori Prize from the International Association for Structural Control and Monitoring in 2014, and numerous best paper awards on national and international conferences. Recently, he has been carrying out several projects on the impact of construction induced vibration on existing hospitals.
