  • Se-Jin Kim won Grand Prize of Research Paper Competition

    Se-Jin Kim received Grand Prize of Research Paper Competition which is provided by Busan Infrastructure Corporation during 2018 International Conference of Cable-supported bridge which was held in BEXCO, Busan city on July 5th. It was great experience to him that a lot of foreign and Korean researchers congratulated him and shared his research accomplishment together. We hope that his work would be able to contribute to real engineering problem.

  • Seminar on Active Vibration Control of Structures Using the Twin Rotor Damper
    Richard Terrill, a research assistant at Hamburg University of Technology gave a presentation on "Active Vibration Control of Structures Using the Twin Rotor Damper." It was a good opportunity to learn about the twin rotor damper (TRD) , an active mass damper that uses the resulting centrifugal forces for vibration control.

  • Sogeumsan Pedestrian Suspension Bridge Field Test
    A joint team of members from TM, Cable Bridge, Kyung Hee University, Mokpo University, and the SNU Structural Design Lab went to the pedestrian suspension bridge in Sogeumsan mountain near Wonju in the Gangwon-do province for a field vibration test (August 3rd-4th). This was done in order to identify and confirm the structural parameters and serviceability. For the Lab this field test was of interest, as the results will be part of the pedestrian bridge research just like the Paju Footbridge field test, which was conducted earlier this year.

  • Jido-Imja Bridges Site Visit

    On July 5th, the lab went to visit the two bridges of the Jido-Imja project currently under construction by POSCO Construction in Sinan County, South Jeolla Province to connect the island Imja to the mainland. Various wind tunnel tests were previously done by the laboratory and the lab was also involved in some of the wind related analysis and design of the bridges, which was done by DM Engineering. After a brief introduction to the local site, cable construction, and construction safety, the visit was conducted by boat. With the successful site visit concluded, the lab is looking forward to further involvement in the ongoing project.
