Seoul National University
Professor Sung-Gul Hong has been a Professor in the Department of Architecture and Architectural Engineering at Seoul National University, South Korea, since 1996. He graduated from Lehigh University in 1994, where he studied strut-and-tie models for bar development and anchorage. Professor Hong is a member of ACI and fib and is currently the national delegate of Korea for fib and a member of the editorial board of the Structural Concrete Journal of fib. He is an active member of fib involved in Committee 4.2.1 on the shear strength of beams and slabs. He authored more than 140 technical publications, including 60 refereed papers in international journals. He has been an expert on concrete plasticity and his papers on strut-and-tie models with their applications have been published in ACI Structural Journal and others. He has been working on both materials engineering and structural applications of ultra-high performance concrete (UHPC) for almost 10 years. He published more than 15 papers on UHPC materials in the Journal of Concrete and Cement Research and other materials journals as well as several papers in structural engineering topics about shear strength in structural journals with book chapters. He has extended UHPC application to seismic retrofit techniques by jacket-strengthening methods for beams, columns, and walls. For the new generation of UHPC, Professor Hong is investigating the properties of UHPC composites with carbon nanotubes, water glass, and various fillers with low thermal conductivities for smart UHPC such as two-stage 3D printing concrete.
National University Of Singapore
Professor TAN KIANG HWEE is a faculty member of the Department of Civil and Environmental Engineering at the National University of Singapore (NUS) since July 1981. He obtained his doctorate degree from the University of Tokyo, Japan in 1985. He specialises in the area of structural concrete and composites and has carried out extensive research on external prestressing, fibre-reinforced polymer (FRP) reinforcement, fibre-reinforced concrete, and sustainable concrete and construction. Professor Tan is a Fellow of the Institution of Engineers, Singapore (IES), Japan Concrete Institute (JCI) and Japan Society of Civil Engineers (JSCE). He is a member of editorial boards for several international journals, including ASCE Journal of Materials in Civil Engineering, ASCE Journal of Composites for Construction, Cement and Concrete Composites, JCI Journal of Advanced Concrete Technology, Science and Engineering of Composite Materials, and others. Currently, he serves as Chairman of Working Group on 'Singapore Standard for Design of Fibre Reinforced Concrete Structures'. He is a registered professional engineer and has also been a consultant in structural engineering and materials to several agencies in Singapore.
