부착식 후 설치 앵커로 연결된 캔틸레버보에 대한 실험적 평가
오홍섭,박성락 한국구조물진단유지관리학회 2011 한국구조물진단학회 학술발표회논문집 Vol.2011 No.9
Recently, there has been a growing interest in expanded sidewalks for bridges within the country. This paper deals with how to optimize the sections of existing cantilever part through the evaluation study of the structured behavior so that the efficiency of the sections is established and the cost cutting of the volume for the unnecessary need of anchor bolts is expected. In its final analysis, it is supposed that there would be some possibilities to improve workability, safety, and economics compared to the existing construction methods.

Nowadays, the necessity of the NDT technique for concrete structure has been increased due to maintenance infra-structure. Therefore NDT instrument for automation of maintenance was focused from now. In this study, internal defeat of concrete structure was investigated by using ultrasonic detection device. In the result of the experimental test, the internal cavity and steel arrangement can be detected and it was possible to adopt the ultrasonic detection method to the maintenance of concrete structure.
