초록

케이블 교량의 거동은 동적 응답에 의해 지배적이며 상대적으로 복잡하므로 교량의 상태를 평가하기 위한 장단기 현장 계측이 요구되는 경우가 빈번하다. 영구적인 SHMS(Structural Health Monitoring System)가 설치되지 않은 경우 성능평가를 위해 이동식 모니터링 시스템이 필요하다. 이 경우 교량의 위치와 형태에 따라 전력, 통신 등의 제한된 여건으로 인해 이동식 모니터링 시스템 운영에 어려움이 발생할 수 있다. 본 연구에서는 국내는 물론 동남아 지역 교량의 장 ‧ 단기 모니터링에 효과적으로 활용될 수 있는 포터블 기반의 스마트 구조응답 모니터링 시스템을 개발하였다. 개발된 시스템은 현장에서 자체 전원 공급 시스템을 이용하여 장시간 운용이 가능한 다채널 휴대용 데이터 수집 및 분석 장비이며, 실시간 데이터를 이용하여 케이블 교량의 동적 특성을 자동으로 분석할 수 있는 알고리즘을 탑재하고 있다. 개발된 시스템의 현장 적용성을 평가하기 위해 한국과 베트남의 케이블 교량에서 현장 실증을 수행하였으며, 이를 통해 개발된 시스템의 현장 운영의 신뢰성과 효율성을 확인하였고, 추가적으로 케이블 교량 모니터링 분야에서의 해외 시장 적용 가능성을 확인하였다.

Because the behavior of cable bridges is dominated by dynamic response and is relatively complex, short- and long-term field monitoring are often required to evaluate the bridge condition. If a permanent SHMS (Structural Health Monitoring System) is not installed, a portable monitoring system is needed for the checking of bridge condition. In this case, it can be difficult to operate the portable monitoring system due to limited conditions such as power and communication according to the location and type of the bridge. In this study, the portable-based smart structural response monitoring system is developed that can be effectively used for short- and long-term monitoring of cable bridges in Korea and Southeast Asia. The developed system is a multi-channel portable data acquisition and analyzer that can be operated for a long time in the field using its own power supply system, and is included with the automated analysis algorithm for the dynamic characteristics of cable bridges using real-time data. In order to evaluate the field applicability of the developed system, field demonstration was conducted on cable bridges in Korea and Vietnam. Through the demonstration, the reliability and efficiency of field operation of the developed system were confirmed, and additionally, the possibility of application to overseas markets was confirmed in cable bridge monitoring field.
