Prof. Mostafa Fahmi Hassanein is an internationally recognized scholar and innovator in steel and composite structures, currently serving as Professor of Structural Engineering at Xihua University, China — on leave from Tanta University, Egypt. He earned his PhD in 2009 from Tanta University, enriched by advanced doctoral training at Luleå University of Technology, Sweden, and has since built a career at the intersection of research, teaching, and industry practice. His global journey includes a visiting professorship at Southwest Petroleum University, China (2019–2020), selection as an innovative talent under Sichuan’s prestigious Tianfu Emei Plan, and recipient of the Foreign Expert Project, Sichuan. Recognized among Stanford University’s Top 2% Scientists worldwide (2020–2024), he also shapes the field through editorial leadership as an Editorial Board Member of Thin-Walled Structures (Elsevier) and Associate Editor of the Journal of Engineering and Applied Science (Springer). With more than 135 international publications, his work directly influences international design codes such as EC3, EC4, AISC, and AS4100, advancing structures that are stronger, more economical, and sustainable across their life cycles. His research thrives on global collaboration, reflecting his belief that innovation emerges where disciplines and cultures meet. His contributions have been honoured with the State Incentive Award in Engineering Sciences (2015), the First-Class Excellence Medal from the Egyptian President (2017), and invitations to speak at leading international events across Europe, Asia, and Africa. He has been recognized as a Consultant Engineer in steel design and featured in Who’s Who in the World, underscoring his standing among the top 3% of professionals in Egypt.
报告内容摘要：
This talk presents a ground-breaking approach for designing concrete-filled steel tubular (CFST) columns under axial compression, introducing the Confinement-Based Direct Design (CBD) method. It begins with a comprehensive review of experimental data across various cross-sections, highlighting the key parameters that govern overall column strength. CFST behaviour is influenced by a complex interplay of factors—geometry, cross-sectional shape, steel type, concrete strength, boundary and loading conditions, and even fibre-reinforced polymer (FRP) sheets. Current design approaches, however, often fail to capture these complexities across the full range of parameters. The CBD method bridges this gap by providing a performance-driven, user-friendly design framework that directly incorporates the lateral confining pressure from the steel tube (and FRP where applicable) into strength calculations. Its predictions have been rigorously validated against experimental datasets and existing design models, demonstrating significantly higher accuracy and reliability. The method currently applies to a wide spectrum of CFST columns: circular and square concrete-filled double-skin columns with ordinary or rubberized concrete, short CFST columns externally strengthened with CFRP or GFRP, CFST columns with welded- or cold-formed stiffened square steel sections, and circular steel tube confined concrete short columns. By capturing the true confining effects, this approach paves the way for more reliable, efficient, and performance-based design of CFST structures.
