Abstract:
This lecture presents background details and selected highlights of the research and development (R&D) on tubular joints conducted at the National University of Singapore (NUS). The research covers plate reinforced joints, thick-walled joints, fabricated trunnions, enhanced partial joint penetration welded joints, grouted joints and nonlinear responses of tubular frames.
The approach adopted in the projects involves particular experiments on test specimens to provide physical evidence and reference results for numerical and theoretical investigations. Some of the R&D results have provided insights and bases for code development, and have been applied to offshore and onshore structural design and construction. The integrative efforts, with significant input from our international collaborators, motivate the NUS team to further contribute towards more cost-effective and safe solutions for the industry and society.

Professor Yoo Sang CHOO is Adjunct Professor in National University of Singapore (NUS) and Distinguished Visiting Professor in Tsinghua University. He is Consultant of Technology Centre for Offshore and Marine, Singapore (TCOMS).
He served as Lloyd’s Register Foundation Chair Professor in NUS from 2009 to 2017. He was the 106th President of The Institute of Marine Engineering Science & Technology (IMarEST) in 2008, and was its first President and Professor as Honorary Fellow from Asia.
Professor Choo was Founding Director of Centre for Offshore Research and Engineering (CORE) when it was set up in NUS, and then served as its Director (Research). He has served in many scientific and technical committees of international organizations, and hosted some of the conferences and symposia. He served as President of Singapore Structural Steel Society, and Society of Naval Architects & Marine Engineers Singapore.
Professor Choo has received international and national recognitions, including two Lifetime Achievement Awards. He and his research team have won best paper and engineering achievement awards. He was honored with Kurobane Award in 2015 from IIW Sub-commission XV-E for his outstanding contributions and achievements in the field of tubular structures.
Professor Choo has served as Principal Investigator in R&D projects, including the Structural Integrity Management Programme on Offshore Structures, and Joint Industry Project on Grouted Joints. He has served as technical consultant or expert witness in major offshore projects. He continues to serve in international committees to develop or revise international standards.
