Structural Health Monitoring of Supertall Buildings

Date, time & venue
2017-03-21;6:00 pm – 6:30 pm (Refreshment), 6:30 pm – 7:30 pm (Talk);Chan Yat Mei Sophie Room, HKIE


Speakers: Dr. Yong XIA, The Hong Kong Polytechnic University



Recent decades have seen the construction of many skyscrapers in China. Although numerical analysis and scaled laboratory experimental techniques have been well developed and employed to predict the structural performance of supertall structures under various loadings, the structural performance under actual construction and service conditions is an issue that has not been investigated in depth to date because of the current shortage of existing, sufficient and mature experience for practical supertall skyscrapers. The recently developed structural health monitoring offers a potential solution as an innovative situ-based laboratory experiment technique that allows for the measurement of a structure’s loadings, environmental factors, and responses. This talk will use the 600-m-tall Canton Tower at Guangzhou as an example to demonstrate the structural behaviors during the construction and service stages, particularly the temperature and wind actions of the supertall structure.


About Speaker:

Dr. Yong Xia is now the Associate Professor of Department of Civil and Environmental Engineering, The Hong Kong Polytechnic University. He obtained his PhD degree from Nanyang Technological University, Singapore in 2002. He then worked at The University of Tokyo as JSPS Fellow and The University of Western Australia as Research Associate, before joining The Hong Kong Polytechnic University in 2006. He has published over 80 refereed international journal papers, secured 5 HK Research Grant Council projects and NNSFC Joint Research Fund for Overseas and Hong Kong and Macao Scholars as the principal investigator. He is now the Co-Editor-in-Chief of Advances in Structural Engineering, an SCI jounral. He was awarded The Nishino Prize in 2013. Dr. Xia’s main research areas include structural health monitoring and nonlinear vibration of cables.
