A Study of Frequency Domain Analysis of Impact-wave for Detecting of Structural Defects in the Concrete Structure

구조물의 안전진단을 위한 충격파의 주파수 영역 탐사에 관한 연구

Impact seismic wave method is a method for non-destructive testing of concrete structure using of stress wave which is propagate and reflected from internal flaws within concrete structure and external surface. In this study, we performed frequency domain method using impact seismic wave test for safety diagnosis of civil engineering structure. And reflection method which is used for one-dimensional target such as tunnel lining and transmission method are compared with each other.
