报告人简介

  Ir Prof Jian-Guo Dai (Associate Head (Academic development) of Department of Civil and Environmental Engineering (CEE), 1 July 2019-Now) graduated with his bachelor’s degree in civil engineering from Dalian University of Technology and his PhD degree in social infrastructure engineering from Hokkaido University, Japan. His research theme is “Emerging materials and structural systems for sustainable concrete infrastructures”. He has received many awards for his research work, including the “Best Basic Research Paper Award” from ASCE, Journal of Composites for Construction in 2005, “Distinguished Young Scholar of FRP Application Committee of Chinese Society of Civil Engineers” etc. Prof. Dai is the contributor of 1 textbook, 4 book chapters, 6 conference proceedings and more than 300 technical papers (including 157 SCI journal papers, Citations at Google Scholar = 7036 and h-index = 43 at Google Scholar as of December 13th, 2021). He has delivered about 40 keynote/invited lectures at international conferences and more than 60 other invited presentations worldwide. In 2020, Prof Dai’s research on eco-friendly concrete coating was highlighted by “Science” in its “Editor’s Choice” and reported by public media like “Ta Kung Pao” and “Hong Kong Economic Journal”. Prof Dai was also in the “World’s Top 2% Scientist-Stanford University Releases List (2021)” (Career and Annual) of the “Civil Engineering” discipline.
Prof. Dai contributes actively his service and leadership to international and domestic technical communities. He serves the International Institution of FRP Composites for Construction (IIFC) as a Vice President, and ISO/TC71 SC6 “Non-traditional Reinforcing Materials for Concrete Structures” as its Committee Manager and served the Asian Concrete Federation (ACF) as the Chair of its Technical Board. He is a Fellow of IIFC, Hong Kong Institution of Engineers (HKIE) and Hong Kong Concrete Institute (HKCI). Currently, he is serving “Journal of Asian Concrete Federation” as a Vice-Editor-in-Chief and “Journal of Advanced Concrete Technology” as an Associate Editor. He also served the journal “Advances in Structural Engineering” as an editor, and “Construction and Building Materials”, “Journal of Materials in Civil Engineering” and few other journals as a guest editor.
 

报告摘要

  Strengthening of reinforced concrete (RC) structures using externally bonded fiber reinforced polymer (FRP) systems has gained widespread acceptance over the past three decades. There are two major types of applications for externally bonded FRP systems: bond-critical applications (e.g. FRP flexural/shear strengthening) and contact-critical applications (e.g., FRP confinement of RC columns). In the bond-critical applications, the bond between the FRP and the substrate concrete plays a critical role in transferring the force from the RC members to the FRP strengthening layer and influences greatly the FRP strengthening efficiency in terms of both the short-term performance and the long-term durability. As the most fundamental issue for the FRP strengthening technology, the bond mechanics of FRP-to-concrete interfaces has received exhausted attention. This lecture presents a state-of-the-art of this topic from fundamental principles to the mechanics involved in predicting the interface debonding failure under various applications.
