On September 23, 2020, the “Innovation Base of Earthquake Engineering Comprehensive Simulation” held a “Cloud Report”, and invited Prof. Rajesh Dhakal, Professor of Structural and Earthquake Engineering at University of Canterbury in Christchurch, New Zealand, to present a report named “Elongation of ductile Reinforced Concrete members under cyclic loading: Causes and Consequences”.
Associate Prof. Jie Xu from the School of Civil Engineering hosted the report. Dr. Junsheng Su of School of Civil Engineering, who invited Prof. Rajesh Dhakal to present this report, delivered a welcome speech.
Through an online classroom, Prof. Rajesh Dhakal gave a review of capacity design of RC frame buildings. The talk includes the experimental and analytical studies conducted at University of Canterbury to understand and account for beam elongation in seismic assessment and design RC building frames. A plastic hinge element developed at University of Canterbury was also introduced that can reliably predict elongation of RC beams/frames and can be used in seismic performance assessment of ductile frame buildings including frame-floor interaction.
The audience at the meeting learnt about the elongation of ductile Reinforced Concrete members. After the report, Prof. Rajesh Dhakal and the audience conducted an online discussion on related issues.
A total of 169 teachers and students participated this “Cloud Report”, including 12 teachers, 114 graduate students, 7 international students and 36 undergraduate students. The audience were from Tianjin University, Hebei University of Technology, etc. After the report, Prof. Rajesh Dhakal and the audience took an online group photo.

Introduction to Dr Rajesh Dhakal:
Rajesh Dhakal is currently a professor of Structural and Earthquake Engineering at University of Canterbury in Christchurch, New Zealand. His current research interests lie in Seismic performance and design of Reinforced Concrete structures, and Development of resilient building systems for seismic loss minimisation. Prof. Dhakal has authored around 400 technical papers in different aspects of structural and earthquake engineering. Prof. Dhakal has received more than a dozen awards including the prestigious Ivan Skinner Award for advancement of earthquake engineering research in New Zealand, and the Otto Glogau Award three times (in 2007, 2011 and 2017) for outstanding publications in the field of earthquake engineering. Prof. Dhakal has delivered keynote speech in five international conferences and has served in the editorial board of multiple international journals, including six years as an Associate Editor of the ASCE Journal of Structural Engineering. He is currently the Chief Editor of the Bulletin of the New Zealand Society for Earthquake Engineering. Prof. Dhakal is a Director of the International Association of SPONSE (Seismic Performance of Non-Structural Elements). He has served in many national/international review/advisory panels, and has contributed to the amendment of design standards in different countries. He is also a Chartered Professional Engineer in New Zealand. Prof. Dhakal was made a fellow of Engineering New Zealand in 2015 and a fellow of the New Zealand Society for Earthquake Engineering in 2017.
