EXPERIENCES OF SLIDING ISOLATION DISK BEARING IN KOREA
Bang In Seok
Biography: Bang In Seok is a director for the Research and Development Center of
ESCORTS Co., Ltd that is a leading company of structural bearing and expansion joint
business in South Korea. He has 20 year experiences in this field and is working as a R&D
coordinator between R.J. Watson, Inc. and ESCORTS Co., Ltd at present. He received his
master degree of civil engineering from Yonsei University in Korea. His research interests
include seismic isolation, seismic fragility analysis and development of new concept isolation
bearings with special materials.
ABSTRACT
Due to recent evidences of increasing activities in Korea and lessons learned from the several
big earthquakes in the neighboring countries, research and application of seismic protection
systems have become more active in Korea. Among such systems, seismic isolation bearings
and passive energy dissipation devices are generally accepted as most effective systems
considering the low to moderate seismicity of Korea. For the most of long span bridges, the
concepts of base isolation and passive energy dissipation have been strongly introduced to
Korean engineers for seismic protection and economic bridge design. Currently, seismic
isolators such as lead rubber bearings, elasto-plastic steel dampers and sliding isolators have
been or are to be installed many bridges in Korea. Among them, sliding isolation disk bearing
(SIDB) has been emerged and in a good reputation as a seismic protection system to Korean
engineers. This paper will review the experiences of the SIDB that have been evaluated by
