PolyU project wins 2022 CSCS Science and Technology Awards Grand Prize
A research team led by Prof. K. F. Chung, Director of the Chinese National Engineering Research Centre for Steel Construction (Hong Kong Branch) and Professor of the Department of Civil and Environmental Engineering at PolyU, won the Grand Award of the China Steel Construction Society (CSCS) Science and Technology Awards 2022.
Applications of the award-winning project, “Basic Theory, Key Technology and International Application of Chinese High Strength 690MPa Steel Structures”, include a number of construction projects in Hong Kong, such as the Double Arch Steel Bridge of the Cross Bay Link in Tseung Kwan O, the long span roof structures of the Kowloon Tsai Swimming Pool, as well as the steel roofs of both the East and the West Stands of the Yuen Long Stadium.
The project provides a comprehensive solution to innovative applications of high-quality Chinese 690MPa steel in construction. With thorough research and development collaboration, advanced predictions on the mechanical properties and structural behaviour of S690 welded sections were achieved through integrated experimental and numerical investigations. This allowed minimal or even no penalty in both strength and ductility in these welded sections after welding. Also, effective design rules were established through rigorous design development and codification.
Prof. Chung’s team successfully completed the research project in collaboration with academics from Tsinghua University and Imperial College London, experts from leading consulting and construction companies in Hong Kong, as well as steel fabricators and suppliers in Mainland China.
