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.

And also he participated in Korean Railroad Bridge Design Code Committee, Korean Harbor Design Code Committee, and Korean Nuclear Power Plant Design Code Committee (KEPIC Code, Korea Electric Power Industry). His researches, especially for the seismic design of concrete bridges and for flexural members under compression, have greatly contributed to the revision of Korean Bridge Design Code and Korean Structural Concrete Design Code. Another code provisions based on his research include ultimate strain and compressive stress distribution of concrete, compressive stress-strain model of confined concrete, material resistance factors of concrete and reinforcement for flexure and compression members, ductility-based shear strength design formula, design equation of required confining steel for seismic design of bridge columns, and reinforcement details of hollow circular and rectangular bridge columns. And also he has been leading a research team of utilizing high strength reinforcement for 8 years, and provided many information to the code revision committees of KCI, ACI 349 and 359 (Nuclear Structure) and the ACI 318-R (High Strength Reinforcement). As an educator, he gave lectures on reinforced concrete, prestressed concrete, and seismic design. And also he wrote two textbooks on reinforced concrete and prestressed concrete.
