Seoul National University, Professor Kang Hyun-gu's Team Wins Best Paper Award at International Architecture and Civil Engineering Conference

Seoul National University announced on the 29th that a research team led by Professor Kang Hyun-gu from the Department of Architecture received the Best Paper Award (T.Y. Lin Award) from the American Society of Civil Engineers (ASCE), the world's leading academic society in the fields of architecture and civil engineering.

The American Society of Civil Engineers is a prestigious global society with a 173-year tradition, which annually selects the best papers in collaboration with international concrete structure societies such as the American Concrete Institute (ACI) and the Precast/Prestressed Concrete Institute (PCI).

The awarded paper is titled "Seismic Behavior of Beam-Column Joints Using Unbonded Post-Tensioning." The research team demonstrated that applying the post-tensioned concrete (PT) method results in over 60% greater strength at the beam-column joints compared to the reinforced concrete (RC) method. This finding provides a foundation for more accurate seismic design when constructing structures using the PT method.

The PT method was introduced to address cracks caused by shaking from earthquakes and other forces, and it is a technique that compensates for the tendency of concrete to deform easily under tensile forces.
