PolyU-led project awarded the largest grant in the latest round of Theme-based Research Scheme

The Faculty of Construction and Environment (FCE) is pleased that a project led by Prof. Jin-Guang Teng of the Department of Civil and Environmental Engineering (CEE) to develop a new type of concrete structures for marine infrastructure has been awarded more than HK$47 million, the largest amount of funding from the Research Grants Council Theme-based Research Scheme 2018/19. The local participating universities will provide more than HK$ 5 million as matching funding, bringing the total budget to above HK$ 52 million. Entitled “Sustainable Marine Infrastructure Enabled by the Innovative Use of Seawater Sea-Sand Concrete and Fibre-Reinforced Polymer Composites,” the project addresses the severe deterioration problem of marine infrastructure caused by steel corrosion by replacing steel with fibre-reinforced polymer (FRP) as the reinforcing material. This replacement then also allows the direct use of seawater and sea-sand in making the concrete (i.e., seawater-sea-sand concrete or SSC). Great environmental and economical benefits can be derived from the use of this new type of structures (referred to as FRP-SSC structures) in marine infrastructure. The research programme will include the development of innovative steel-free structural forms as well as new methods for the design, construction and performance monitoring of FRP-SSC structures. A key scientific challenge for the team is the establishment of a multi-scale, multi-physics approach for predicting the long-term performance of FRP-SSC structures in a marine environment over a service life of more than 50 or even 100 years. Results obtained with this method will assist greatly in the formulation of safe and economical design methods for FRP/SSC structures. Co-principal investigators include Prof. Christopher Leung from the Hong Kong University of Science and Technology, Prof. Zongjin Li from the University of Macau, CEE colleagues Prof. Yiqing Ni and Prof. Chi-sun Poon, Dr Florence Sanchez from Vanderbilt University in the US, Prof. Tong Sun from the University of London, Mr Sheng-Nian Wang of the CCCC Fourth Harbour Engineering Institute Co. Ltd. in mainland China, and Prof. Limin Zhou of the Department of Mechanical Engineering. Since the Theme-based Research Scheme began in 2011/12, PolyU has had 2 projects funded by this highly competitive scheme, in 2017/18 and 2018/19 respectively, both with the theme of developing a sustainable environment. The previous winning project was led by Prof. Tao Wang of CEE.

How to enhance efficiency in tree management?

Under the PolyU-led Jockey Club Smart City Tree Management Project, Smart Sensing Technology (SST) and Geographic Information Systems (GIS) will be applied in monitoring the stability of trees. Dr Charles Wong at the Department of Land Surveying and Geo-Informatics talked about the significance of this project.

FCE to apply smart sensing technology in urban tree management

The Hong Kong Polytechnic University (PolyU) kicked off the Jockey Club Smart City Tree Management Project, a large-scale pilot project in Hong Kong, with the support from academia, non-government organisations (NGOs) and the Government, to apply smart sensing technology (SST) and Geographic Information Systems (GIS) for monitoring tree stability to enhance timely appropriate mitigation measures for sustaining longer tree lives. Tree anchorage is critical to its structural stability. Weak anchorage will be reflected in a tree tilting, which in serious case poses the hazard of falling. In the Project, sensors will be tailor-made and installed on the lower trunk of selected urban trees to monitor their tilting angle in a 3-dimensional manner, as a way of assessing the stability of the root and thus the tree. Data will be collected for a quantifiable analysis of the trees’ root plate movement through the use of SST, i.e. the technology of monitoring environmental changes with the use of remote sensors and techniques, via the GIS-based platform. Taking into consideration of various environmental factors, a threshold will be determined to design the monitoring system as a scientific measurement of the root plate movement and stability. When the tilting angle of a tree exceeds the threshold, the project team will be alerted to conduct a visit to verify the data for the purpose of calibrating the system. When considered necessary, it will inform the relevant tree management team to undertake actions in a timely manner. As such, the information generated by the monitoring system will provide objective and quantifiable data for the consideration of the tree management team to supplement the visual tree monitoring method widely adopted by the industry at the moment in assessing the movement of a tree.

Dean (FCE) received Guanghua Engineering Science and Technology Award

Professor You-Lin Xu, Chair Professor of Structural Engineering at The Hong Kong Polytechnic University (PolyU), has been bestowed the 12th Guanghua Engineering Science and Technology Prize by the Chinese Academy of Engineering (CAE). The award presentation ceremony took place on 30 May 2018 in Beijing. The biennial national prizes aim to reward Chinese engineers and scientists who have made outstanding achievements and important contributions to engineering technology and engineering management. Established in 1996, the award has been extended to include candidates from Hong Kong, Macau and Taiwan for the first time in the last session. This year, 30 awardees were selected from 296 candidates for the top honour. Professor Xu is one of the three award recipients from Hong Kong. All the three Hong Kong awardees are nominated by the Hong Kong Academy of Engineering Sciences. With over 30 years of experience in research and consultancy work in structural engineering, Professor Xu is internationally renowned for his contributions in wind engineering, earthquake engineering, structural vibration control and structural health monitoring. Over the years, he has participated in over 80 national and international research projects, including providing consultation on wind and structural health monitoring of the Tsing Ma Bridge and Stonecutters Bridge in Hong Kong, as well as the Shanghai Tower in the Chinese mainland — the second tallest building in the world. Professor Xu joined PolyU in 1995 as Assistant Professor, and is presently the Dean of Faculty of Construction and Environment. He has obtained two patents on his inventions and has published more than 280 international journal papers. He has garnered many prestigious awards in his career, including the Croucher Senior Research Fellowship in 2006, the Qian Ling Xi Computational Mechanics Award from the Chinese Association of Computational Mechanics in 2010, the Robert H.

FCE professors speak on opening up Chinese mainland funding for Hong Kong

In a TVB news programme on opening up Chinese mainland funding for Hong Kong, a number of researchers from local universities were interviewed. Professor Chung Kwok-fai, Associate Head of PolyU’s Department of Civil and Environmental Engineering (CEE), also Director of the Hong Kong Branch of Chinese National Engineering Research Centre for Steel Construction at PolyU, said the Chinese mainland has been producing high performance steel materials over the years, and the Centre has helped promote wider use of such materials in overseas projects. Leveraging the opportunities of the Greater Bay Area development, the Centre will be able to nurture more professionals, helping to enhance the overall level of skills and technology of the steel construction industry. Professor Ni Yiqing from CEE, also Director of the Hong Kong Branch of Chinese National Engineering Research Centre on Rail Transit Electrification and Automation at PolyU, said the Centre focuses on developing advanced rail technologies to enhance the safety and reliability of China’s high speed rail. With increased funding support from the Central Government, the research team expects to participate in more railway projects at the national level in future.
