报告摘要：There is currently no effective guidance to prevent structural collapse caused by the localized failure of a primary structural member following a terrorist attack. This study proposes a reliable and efficient evaluation method for assessing the progressive collapse resistance of seismically designed structural systems in accordance with the Korean Building Code (KBC). The results indicate that a steel moment-resisting frame designed per KBC 2016 satisfies the required performance criteria for progressive collapse resistance. However, in scenarios involving the removal of two adjacent columns, adequate performance can be ensured through the use of welded cover plate flange (WCPF) connections.The modeling and analysis methods presented in this study can be effectively applied to progressive collapse assessment. Structural collapse resistance can be evaluated in a straightforward and quantitative manner using the proposed metrics of structural robustness and sensitivity. Therefore, the findings are expected to be valuable for future research and practical structural design related to progressive collapse prevention.
报告人简介：Professor Noh, Sam-Young is a faculty member in the Department of Architecture and Architectural Engineering at Hanyang University, South Korea. He earned his Ph.D. in Structural Engineering from RWTH Aachen University in 2001, following a Dipl.-Ing. from Dortmund University (1993) and a Bachelor’s degree from Hanyang University (1986). His academic career spans over two decades, including roles as a Visiting Scholar at the U.S. National Institute of Standards and Technology (2011–2012) and research positions at the Institute for Statics & Dynamics at RWTH Aachen and Bochum University (2000–2003; 1995–2000). His expertise lies in structural mechanics, nonlinear finite element analysis (FEM), and the numerical modeling of complex structural materials. His pioneering research focuses on the theory and failure mechanisms of shell structures, as well as simulating structural collapse under extreme conditions. His work has significantly influenced both academic research and industry practices, solidifying his reputation as a leader in structural engineering innovation.
