Introduction
On November 16, 2023, the 5th NEXCEL Series Forum on FRPs for Civil Engineering was hosted by NEXCEL. Two renowned experts and one NEXCEL Project Principal Investigator were invited to deliver reports on fiber-bridging interface for connecting FRP profile and concrete, comprehensive promotion of FRP materials and engineering structural members and 3D geometrical interpretation of analysis-oriented models for FRP confined concrete. This forum was chaired by Prof. Feng Peng, Dean of Civil Engineering, Tsinghua University and member of NEXCEL Technical Advisory Committee (TAC), and Dr. Li Juan, Program Director of NEXCEL. This forum attracted active participation of more than 4000 viewers.
Dr. Lin Hongwei, Associate Professor of Beijing Jiaotong University, delivered a speech entitled “Mechanical properties of a newly developed fiber-bridging interface for connecting FRP profile and concrete”. Dr. Lin introduced a novel FRP-concrete fiber-bridging interface, incorporating CFRP fabric and epoxy resin in the interlayer, and achieved improvement in the mechanical performance of the structure by AI modeling.
Professor Liu TianQiao from Beijing University of Technology made a presentation on “Comprehensive promotion and improvement of FRP reinforced composite materials and engineering structural members”. Professor Liu focused on several key techniques such as enhancing the elastic modulus and connectivity of pultruded FRP members and rebars, design of composite structures with ductile failure and flame-retardant properties, as well as improving the creep resistance of FRP.
Dr. Yang Jia-Qi, Associate Professor of China University of Mining & Technology, Beijing, offered a report entitled “3D geometrical interpretation of analysis-oriented models for FRP confined concrete”. Dr. Yang provided a detailed 3D geometrical interpretation in three aspects: stress-strain models, path dependency of FRP-confined concrete, and Poisson Effect of FRP tube, which provides a reference for scholars in the theoretical analysis of FRP concrete
In the final Salon/ Q&A session, experts engaged in discussions with online scholars on issues related to ductile failure of brittle materials, enhancing the interface adhesion between FRP and concrete, and the fire resistance of FRP profiles, etc. The forum concluded successfully with hot discussions.
