초록

세계적으로 많은 수의 콘크리트 구조물이 건설되어 사용되고 있다. 구조물을 안전하고 지속적으로 사용하기 위해서는 꾸준한 점검과 유지관리가 필요하다. 인력을 활용한 점검과 유지관리 기법은 효율적이긴 하지만, 현장 점검이 이루어지는 시점에 대한 단속적인 상태에 대한 점검만 가능하다. 이에 구조물의 상태를 연속적으로 모니터링 할 수 있는 시스템의 필요가 높아지고 있다. 따라서, 콘크리트 구조물의 표면에 전도성도막을 설치하여 균열 및 손상의 탐지하는 연구를 수행하였다. 콘크리트 구조물의 구조적 특성을 반영하여 균열의 발생과 진전을 모니터링 할 수 있는 병렬저항 형식의 균열감지패턴을 개발하였고, 이에 대한 실증연구를 수행하였다. 철근콘크리트 보부재를 제작하여 균열감지패턴을 설치하였고, 하중가력실험을 통해 균열 모니터링의 가능성을 검증하였다.

A large number of concrete structures are built and used around the world. To ensure their safe and continuous use, these structures require constant inspection and maintenance. While man-powered inspection and maintenance techniques are efficient, they can only provide intermittent status checks at the time of on-site inspection. Therefore, there is a growing need for a system that can continuously monitor the condition of the structure. A study was conducted to detect cracks and damage by installing a conductive coating on the surface of a concrete structure. A parallel resistance pattern that can monitor the occurrence and progression of cracks was developed by reflecting the structural characteristics of concrete structure. An empirical study was conducted to veryfy the application of the proposed method. The crack detection pattern was installed on the reinforced concrete beams, and the crack monitoring method was verified through applying a load on the beams.
