Dr. Kai Qian is Professor in the College of Civil Engineering and Architecture at Guilin University of Technology. He received his Ph.D. in civil engineering in 2013 from Nanyang Technological University, Singapore. Then, he worked as Post-doctoral Researcher at Nanyang Technological University during 2013-2015. He was granted by the National Outstanding Youth Fund of China since 2020.Prof. Kai Qian is Vice President of the Youth Committee of China Seismological Society for Infrastructure Earthquake Prevention and Disaster Reduction, Director in American Society of Civil Engineers (ASCE), Singapore branch, Member in ASCE/SEI Disproportionate Collapse Tech. Committee, Member in ASCE/SEI Multihazard Mitigation (MHM) Committee, etc.; he is on the editorial board of several international journals.Prof. Kai Qian has been teaching and conducting research on design of concrete structures including precast concrete and prestressing concrete structures. His research interest focuses on progressive collapse mitigation of concrete structures, seismic strengthening, and retrofitting of existing structures. He is PI of 3 projects supported by National Science Foundation of China. He has authored over 90 research articles. In addition, he served as Adviser to many Ph.D. and master’s students.Dr. Qin Fang is Professor of Civil Engineering at the Army Engineering University of PLA, China. He earned his Ph.D. in civil engineering from PLA University of Science and Technology, China.Dr. Fang has more than 40 year’s experience in teaching and researching in the aspect of blast-resistant structures. His main research interests are focused on the protective structures under severe dynamic loads, including considerations of both survivability and fragility aspects of military and civil facilities subjected to projectile penetration, blast and shock impact. He has written more than 400 journal and conference papers and published three books. His work has been widely used in the construction of the facilities and also applied in Chinese codes for blast-resistant structures.Currently, he is a fellow of the International Association of Protective Structures and served as a member of the executive board of International Association of Protective Structures and vice chairman of the Protective Engineering Division of China Civil Engineering Society.
