The afternoon of March 22, 2019,Professor Lin-hai Han, Vice Dean of Civil and Water Conservancy College of Tsinghua University, was invited to give an academic report entitled "Principles and Engineering Application Research of Concrete Filled Steel Tube Mixed Structures".The report was chaired by Professor Hu Heng, Vice Dean of ourcollege.
Professor Han Lin-hai expounded the research process and achievements of the design principle of concrete filled steel tube (CFST) mixing structure from the aspects of research background, experimental design, numerical model, mechanism analysis, calculation method and engineering application.The report was full of pictures and texts, and covered all levels of materials, components and structural systems involved in the research and application of CFST hybrid structures.Contents of the report includednot only short-term impact problems but also long-term durability problems, and put forward the process control concept of "trinity" of concrete quality in CFST structure.The research results have provided scientific suggestions and theoretical guidance for practical projects of Labajin Bridge (the world's longest CFST stiffened composite structure pier), Heishigou Bridge, Sliding Cable Bridge of Jinsha River in Butuo County and Ganmeizi Bridge (the world's longest CFST truss bridge).
During the discussion session, teachers and students had in-depth exchanges and consults with Professor Han.The atmosphere at the scene reached its climax.
This academic report gives students a comprehensive understanding of the latest achievements in the research and application of CFST hybrid structures and the scientific frontiers in this field. It broadens the academic horizon and plays an important role in promoting students' academic thinking, innovation awareness and research capabilities.
