From Hazards to Disasters: A Need for a Culture of Resilience
报告人：Ahsan Kareem 教授
Most hazards become disasters due to the vulnerability of communities, Hurricane Katrina is a good example. In recognition of the increasing impact of disasters and their complexities there is a critical need to enhance resilience of communities to disasters which involves both technical and societal issues. Community resilience can be viewed at three dimensions that are interrelated: having a low probability of failure, minimizing the severity of negative consequences of disasters and recovering expeditiously from the impact of disasters. A framework of resilience for a built environment involves assessing the impact of multiple natural and manmade hazards, degradation and potentially climate change in terms of established performance goals, mitigation, response and recovery. The lecture would include examples of hazards leading to disasters, modeling portfolios couched in cyberinfrastructure, mitigation, response and recovery and a sample of suggested changes in classical engineering approach to design thinking tied to performance based design.
Ahsan Kareem is the Robert M. Moran Professor of Engineering and the Director of the NatHaz Modeling Laboratory at the University of Notre Dame. His work focuses on characterization and formulation of dynamic load effects due to wind, waves and earthquakes on tall buildings, long span bridges, offshore structures and other structures via fundamental experimental, laboratory and full-scale measurements utilizing cyber and cyber-physical infrastructures. He is elected President of the International Association for Wind Engineering (IAWE). He has been awarded numerous honors, including the Presidential Young Investigator Award from the White House Office of Science and Technology. A recipient of ASCE’s: Theodore von Karman Medal, Masanobu Shinozuka Medal, James Croes Medal, Robert H. Scanlan Medal and Jack E. Cermak Medal and State-of-the-Art Award, inducted to the Offshore Technology Conference Hall of Fame and Distinguished Member of ASCE; Alan G. Davenport Medal of IAWE; Distinguished Research Award of IASSAR (Int’l Assoc. for Structural. Safety and Reliability); the University of Notre Dame. He has served as a High-End Foreign Expert at Tongji University and delivered 2013 Scruton Lecturer at the Institute of Civil Engineers, London, UK. He has been appointed Honorary Professor at several universities overseas, serves on the Editorial Board of several international journals and has recently co-authored two books. He is an elected Member of the US National Academy of Engineering.
