PRESANTATION ABSTRACT:
Fibre-reinforced polymer (FRP) composites have been widely used in the strengthening/retrofit of structures. This success has been due to their many advantages, which include their excellent corrosion resistance and high strength-to-weight ratio as well as the possibility to tailor their properties in different directions to achieve the best structural performance. The success of FRP composites in the strengthening/retrofit of structures has also led to many studies exploring their potential in the construction of new structures. A promising direction for the use of FRP composites in new construction is to create new structural forms based on the combined use of FRP, steel and concrete in an optimal manner. This talk will present two innovative hybrid structural member forms incorporating FRP composites, namely, hybrid FRP-concrete-steel double-skin tubular columns and FRP-confined concrete-filled steel tubes. In these hybrid structural members, FRP are optimally combined with steel and concrete so that its disadvantages are minimised while its advantages are appropriately exploited. As a result, these hybrid members possess excellent corrosion resistance as well as excellent ductility and seismic resistance. This talk will explain the rationale and advantages of the two forms of structural members and present a summary of the recent and current studies on their structural behaviour and design.
ABOUT THE PRESENTOR - brief biography:
Dr. Tao Yu is a Senior Lecturer at the University of Wollongong (UOW) in Australia, and an Associate Editor of the international journal Advances in Structural Engineering. Dr. Yu received his BEng degree in 2001 from Zhejiang University and his PhD degree in 2007 from The Hong Kong Polytechnic University. His PhD research was on a novel form of hybrid structural members incorporating FRP, concrete and steel, and included experimental, numerical and theoretical investigations into various aspects of the novel structural members. After his PhD study, Dr. Yu has expanded the scope of his work to various branches of structural engineering, including other forms of hybrid structures, the rehabilitation of existing concrete and steel structures, the seismic assessment/retrofit of concrete structures, and the nonlinear numerical simulation of various structural problems. Dr. Yu’s research publications in the area of structural engineering include 30 SCI-indexed journal papers in refereed international journals, 2 book chapters and 36 papers in international conference proceedings. Among the 30 journal papers, 6 are among the “Most Cited Articles”, “Top 25 Hottest Articles”, or “Top Downloads” of the respective journals (i.e. Engineering Structures; Journal of Composites for Construction, ASCE; Journal of Constructional Steel Research; Construction and Building Materials). While most of his journal papers were published in the past six years, these papers have received a total of 281 non-self citations in Web of Science, with an h-index of 11. Dr. Yu is also one of the main contributors for the Chinese national standard Technical Code for Infrastructure Application of FRP Composites (GB50608-2010) and the Hong Kong design guideline Guide for the Strengthening of Concrete Structures using FRP Composites. Dr. Yu has successfully secured a number of research projects as a principal investigator, chief investigator or co-investigator, receiving a total amount of around RMB 10 million. These include the recent project he secured (receiving around RMB 2 million) as the sole chief investigator from the Australian Research Council through its “Discovery Early Career Researcher Award” scheme, which is a quite competitive scheme with a successful rate of below 15%.
