Professor Hyeonjong Hwang from Department of Architecture at Konkuk University received New Researcher’s Award at Korea Concrete Institute for his recent research achievements on reinforced concrete structures. He also won Thesis Award from Korea Institute for Structural Maintenance and Inspection.In his thesis ‘Effect of Impact Load on Splice Length of Reinforcing Bars’, Professor Hwang discovered that bond behavior due to strain rate effect and structural damage occurs when extreme loads such as shock or explosions affect concrete structures. Professor Hwang also developed a design formula for actual structure design and safety assessment.
Professor Hwang the world’s first experiment relating drop hammer test and attachment test to evaluate bond behavior of reinforced concrete when low-speed impact is applied to supporting parts of the concrete structure through his thesis ‘Effect of Loading on Bar Development Length in CCT node’, and revealed changes in the attachment strengths of reinforced concrete during impact load.
