Activity report 2: International Symposium on Bridge Technologies for Next Generations

A symposium on ‘Bridge Technologies for Next Generations’ was held in Seoul National University, Korea on Aug. 22, 2017. In last 25 years, engineers and researchers in Korea have made outstanding developments in various bridge technologies. In particular, research centers including the Korea Bridge Design and Engineering Research Center played a major role in developing core technologies such as reliability-based limit-state design standards for bridge systems including long-span cable bridges, and disaster-resilience of cable bridges against natural and man-made hazards. During this period, bridge engineering communities in Japan and Korea had active collaborations in various aspects, which led to remarkable outcomes and strong collaborative networks. This symposium targeted to further strengthen the friendship and contribute together to bridge engineering communities in Asia and the world by developing next-generation technologies. Celebrating the achievements and collaborations in last 25 years, this international symposium brought together some of the most prominent scholars and engineers to discuss future directions of technological developments in design, construction, monitoring and maintenance of regular and cable bridge systems.

Activity report 3: Special Session in ISSS-2017

A special session on ‘Advanced Technologies for Construction & Maintenance of Steel Bridges’ and ‘Numerical Analysis, Measurement and Control of Structural Vibration’ were held in the 9th International Symposium on Steel (ISSS) at Jeju in Korea, during Nov. 1-4, 2017, for the mutual communication and cooperation between committee members and colleagues. The session on ‘Advanced Technologies for Construction & Maintenance of Steel Bridges’ was proposed by Prof. Eiki Yamaguchi (JSCE, Representer) and JSCE, KSCE and CICHE were participated as speakers. The Chair of TC-18, Prof. Ho-Kyung Kim was serving as the chairman of Local Organizing Committee of this event.

Next plan 1: Organization of a Special Session in IABMAS 2018, Melbourne

A special session on ‘Assessment and Evaluation of Deteriorated Bridges’ is being organized in 9th International Conference on Bridge Maintenance, Safety and Management (IABMAS) 2018, July 9-13. Prof. Ho-Kyung Kim (KSCE, Chair of TC-18)) proposed this session and Prof. Eiki Yamaguchi (JSCE, Representative), Mr. Taku Hanai (JSCE, member), Prof. H. Katsuchi (JSCE, member), Prof. Yu-Chi Sung (CICHE, Representative) will attend as presenters.

Next plan 2: Organization of a Special Session in CECAR8 2019, Tokyo

Unfortunately, TC-18 missed to encourage each member to submit papers to CECAR8. Chair Ho-Kyung Kim will contact to the secretariat and, if accepted, will consider having a special session on ‘Recent Developments in Long-Span Bridge Technology and Toward Resilient Operation’.
