Organized Session

(OS1) Title : High Performance Steel Structures

Organizer:
Gang Shi (Tsinghua University, China)

Summary

This session focuses on the researches related to high performance steel structures. “High performance steel” (HPS) herein includes high strength steel, stainless steel, weathering steel, fire-resistant steel, high-toughness steel, low-yield-point steel, memory alloy steel, additive manufacturing steel and other types/grades of steel used in construction different from low grade carbon steel.
(OS2) Title : Protective Structures and Safety

Organizer:
Sungkon Kim (Seoul National University of Science and Technology, Korea)

Summary

Mission of the protective design is on protecting life, property, facility, system device and operations by developing protective design measures that reduce threat level and vulnerability while enhancing structural resilience. Protective design procedure against blast, CBR or EMP hazard would be accomplished with the threat identification, risk-based assessment, and designing the members and structures based on the proper design requirements. This session will address the relevant issues on protective structures for ensuring proper protective performances. And also the issues on the consequences management for reacting against security threats.
(OS3) Title : Vibration Control and Rehabilitation of Aged Steel Railway Bridges

Organizer:
Namhyung Lim (Chungnam University, Korea)

Summary

Open deck steel railway bridges, one of the most representative old steel bridge type, are still in service in many countries. In this session, topics on how to reduce vibration and how to rehabilitate the old open deck steel railway are discussed.
(OS4) Title : Smart Materials and Devices and Their Applications

Organizer:
Eunsoo Choi (Hongik University, Korea)

Summary

This session will highlight interesting topics of smart materials, devices, and applications to improve dynamic responses or seismic performances of structures, namely bridges and buildings. In particular, papers related to shape memory alloys (SMAs) will presented to broaden your knowledge of basic material characteristics of SMAs, developing smart devices using SMAs, and improving seismic response of structures using SMAs’ applications. Additionally, papers related to other materials to develop smart devices will be also discussed. The presenters and attendants will share the basic and advanced information of SMAs and their applications.
(OS5) Title : Steel Bridge Rehabilitation

Organizer:
Masahiro Sakano (Kansai University, Japan)
Kab- Soo Kyung (Korea Maritime and Ocean University, Korea)

Summary

In this special session, several papers on evaluation, assessment, repair and retrofit of fatigue and corrosion damage in steel highway and railway bridges will be presented and discussed. We have a number of steel highway and railway bridge structures especially in urban area in Korea and Japan. Some of those structures suffer various types of fatigue and corrosion damage, but replace of them should be too expensive, and restriction or close of the traffic could be hardly allowed. So, rehabilitation of those structures becomes of urgent and great importance.
Speakers will be professors and experts on steel bridge structures who are working in universities, expressway companies and railway companies.
(OS6) Title : Fire-Resistance Design and Construction of Steel and Composite Structures in Korea

Organizer:
Sungmo Choi (University of Seoul, Korea)

Summary

This special session introduces and discusses the fire-resistance design and recent research on the fire performance of steel and composite structures in Korea through several papers. Recently in Korea, many buildings are constructed using a variety of innovative construction methods, including not only composite columns and beams, but also composite floor systems and foundations. Normally, composite structures have superior fire-resistance performance compared to steel structures, so we want to take advantage of their fire-resistance performance. Therefore, researches on the fire-resistance performance of the composite structure are urgent and very important.
Speakers will include professors and experts in fireproof structures working in universities, construction companies, and offices of structural engineers.
(OS7) Title : Fatigue Performance of Clamps in the Rail Fastening System

Organizer:
Hyoung-Bo Sim(Incheon National University, Korea)
Yeun Chul Park(Hannam University, Korea)

Summary

This special session will present and discuss several papers on the fatigue performance of clamps in the rail fastening system. The fatigue failure of clamps has been reported during service in some railway lines. Since the clamp of a rail fastening system is a key element to tie the rail to the sleeper, the clamp design must prevent fatigue cracks because their failure can significantly affect the safety of trains. This special session will discuss the topics including the cause of the fatigue cracks in the clamps with some fatigue test results, reliability analysis with field measurements in the railway tracks, and effects of the depth of decarburized layer in the clamp on the fatigue strength.
(OS8) Title : Advances in Bridge Engineering and Technologies

Organizer:
Eiki Yamaguchi (Kyushu Institute of Technology, Japan)

Summary

Recent advances in bridge engineering and technologies are presented. Specifically, various issues associated with the design, analysis, construction and maintenance of steel bridges are discussed. Not only academic work but also practical work is considered very important.
