응력파 기반 Impact Echo Method를 이용한 콘크리트 구조물의 내부 결함탐사에 관한 연구

Abstract

As infrastructures are being deteriorated, non-destructive evaluation of existing structures and construction quality control are increasingly demanded. This paper is to study Flae detection technique of concrete members using Impact Echo method. This technique is based on stress wave propagation. Experiments were performed using three types of concrete members that have simulated damages at known locations for tests and analysis. Test results are evaluated and summarized in this paper.
