ABSTRACT
ABSTRACT: In Korea, there has been a wide consensus about the necessity of bridge monitoring system primarily due to a chain of accidental bridge collapses since a decade ago. The 1st generation bridge monitoring system was originated from instrumentation system introduced upon the reconstruction of New Haengju Bridge after its sudden collapse in 1995. On-line instrumentation system installed in existing cable-supported bridges including Namhae Bridge, Jindo Bridge and Dolsan Bridge can be considered as the 2nd Generation Bridge Health Monitoring System (BHMS), which is followed by the development of 3rd generation bridge monitoring system represented by Seohae Bridge and Yeongjong Bridge in use to date. This paper tracks the background about the advent of Korean bridge monitoring system and its developmental history until now; brings up the current associated studies in progress and limitations of contemporary BHMS technologies as well; and thereby suggests possible remedial solutions for follow-up bridge monitoring system.
