Abstract
In order to investigate the structural defects of a cylindrical-type toluene storage tank, we carried out the acoustic emissions. The storage tank was manufactured with high strength steel in 1978 and its's first and second courses from bottom were entirely repaired, recently. Acoustic emissions were monitored with real time according to load sequences in the
원통형 톨루엔 저장탱크의 구조결함을 조사하기 위하여 음향방출시험을 수행하였다. 원통형 저장탱크는 고장력강으로 제작되었으며, 최근에 저장탱크의 하부 1 및 2단은 전면 보수되었다. 음향방출은 최대설계하중의
