Mercredi 5/09/2018: Conférence "Resilience and Robustness of Civil Engineering and Marine Structures against Extreme and Accidental Conditions"

05/09/2018

The department UEE is pleased to invite you to the lecture given by JK Paik, Prof. at Pusan National University (Korea), Prof. at University College London (UK), Doctor Honoris Causa of ULiège, "Resilience and Robustness of Civil Engineering and Marine Structures against Extreme and Accidental Conditions".

 

Abstract

Structural safety studies under extreme and accidental conditions are associated with VUCA which is an acronym that stands for volatility, uncertainty, complexity and ambiguity. Volatility indicates the nature and dynamics of change which is various, significant, frequent and rapid. Consequences of structures in extreme and accidental conditions are volatile because a number of random variables are involved, they are time-variant and space-variant, and their characteristics are dynamic or impact happening during a very short period of time. Uncertainty indicates a situation in which hazards and their consequences are unpredictable. Random variables cannot be defined with 100% certainty because they are uncertain. Complexity means the involvement of multi-physics, multi-scale and multi-criteria due to multiple factors affecting the situations which may be intricately interacted. Structural consequences under extreme and accidental conditions are complex because they are affected by a number of factors which are highly nonlinear and do not necessarily follow Gaussian aspects. Ambiguity means a lack of clarity due to the haziness of reality, the potential of misreads or the difficulty of understanding the situation. Extreme and accidental conditions and their consequences are difficult to manifest because they are ambiguous.

 

To assess integrity and safe performance of structural systems under extreme and accidental conditions in VUCA environments, advanced technologies should be applied by smart processing of information with database that may be vague, unfamiliar and dynamic. Most of all, it is important to convince that the VUCA environments can be controlled and managed by advanced science and technology.

 

In engineering community associated with structural safety studies, mathematical modeling techniques are used to manage the VUCA environments. Volatility can be dealt with through the relevance of random variables in the mathematical model that formulate the system behavior. Uncertainty can comprise two groups: inherent uncertainty and modeling uncertainty. Inherent uncertainty is caused by natural variabilities in environmental actions and material properties, and modeling uncertainty arises from inaccuracy in engineering modelling. Complexity can be managed by computational models which suit today’s computer powers. Ambiguity can be minimized by processing big database which can be obtained from the collation of historical events, and/or otherwise from relevant generation of artificial database. In this lecture, the speaker is going to share his insights and knowledge on advanced structural safety studies.

 

 

Biography

 

Dr. Jeom Kee Paik is Professor of Safety Design and Engineering at the Department of Naval Architecture and Ocean Engineering of Pusan National University and Professor of Marine Technology at the Department of Mechanical Engineering of University College London. He is an honorary professor at University of Strathclyde, at University of Aberdeen, and at Southern University of Science and Technology in Shenzhen, China.

 

Prof. Paik’s research interests include nonlinear structural mechanics, analysis, and design; advanced safety studies; limit state-based design; structural reliability; risk assessment and management; health condition assessment and management; fires, explosions, collisions, grounding, dropped objects, and impact engineering; corrosion assessment and management; structural longevity; inspection and maintenance; and decommissioning.

 

 

Prof. Paik has authored or coauthored more than 500 technical papers including over 270 peer-reviewed journal articles. He is the coauthor or coeditor of five books: Ultimate Limit State Design of Steel-Plated Structures (with A.K. Thayamballi), John Wiley & Sons, 2003; Ship-Shaped Offshore Installations: Design, Building, and Operation (with A.K. Thayamballi), Cambridge University Press, 2007; Condition Assessment of Aged Structures (with R.E. Melchers), CRC Press, 2009; Ship Structural Analysis and Design (with O.F. Hughes), SNAME, 2013; and Ultimate Limit State Analysis and Design of Plated Structures, John Wiley & Sons, 2018. He also obtained numerous patents based on his research studies over a wide range of topics in naval architecture and ocean engineering.

 

 

Among other recognitions, Prof. Paik received both the William Froude Medal of the UK Royal Institution of Naval Architects (2015) and the David W. Taylor Medal of the US Society of Naval Architects and Marine Engineers (2013), the two most prestigious medals in the global maritime community in recognition for his contributions to naval architecture and ocean engineering. He was conferred the Doctor Honoris Causa (Honorary Doctorate) by the University of Liege in Belgium (2012) in recognition for his contributions to international science, engineering, and technology. Prof. Paik was awarded the Republic of Korea Order of Science and Technology Merit (2014). He has received numerous (13) best paper awards and engineering prizes from the SNAME, the RINA, the UK Institution of Mechanical Engineers, the American Society of Mechanical Engineers, and the Society of Naval Architects of Korea. As a very special honor for a living figure, the RINA created a prize named in honor of Prof. Paik, the Jeom Kee Paik Prize, which has been awarded each year since 2015 for the best paper on structures published by a researcher under 30years of age; the prize is the first of its kind named for a non-Briton in the RINA’s 156-year history.

 

 

Prof. Paik has served in numerous international engineering societies in various capacities. He served as editor-in-chief of UNESCO’s Encyclopedia of Life Support System with EOLSS 6.177 Ships and Offshore Structures in 2006–2011. He served as chairman of the Korean Shipbuilding Advisory Committee of Registro Italiano Navale (Italian Classification Society) in 2013–2014 and the numerous technical committees of the International Ship and Offshore Structures Congress (ISSC) associated with Ship Collisions and Grounding (2000–2003), Condition Assessment of Aged Ships (2003–2006), and Ultimate Strength (2006–2012). He has presided numerous international conferences, including the International Conference on Thin-Walled Structures (ICTWS 2014, Busan, Korea) and the International Conference on Ocean, Offshore, and Arctic Engineering (OMAE 2016, Busan, Korea), and has cochaired the International Conferences on Ships and Offshore Structures. He will chair the upcoming International Symposium on Plasticity and Impact Mechanics (IMPLAST 2019, Busan, Korea).

 

 

Currently, Prof. Paik heads the Korean Technical Committee of ClassNK (Japanese Classification Society), and is a member of the Academic Advisory Council of Universiti Teknologi PETRONAS in Malaysia and of the ISSC Standing Committee. Prof. Paik is Founder and Editor-in-Chief of Ships and Offshore Structures journal and an editorial board member for more than 20 international journals.
