Shaking Table Test of Steel Cylindrical Liquid Storage Tank Considering the Roof Characteristics

다국어 초록 (Multilingual Abstract)

Steel cylindrical tanks are widely used for the storage of hazardous substances of which leakage must be prevented under any circumstances. However, the dynamic response of the steel cylindrical liquid storage tank depends sensitively on the fl uid– structure interaction and the vibration of the tank structure and necessitates clarifi cation for the safety of the tank structure.
This paper presents the results of shaking table tests performed to examine the dynamic behavior of a scaled cylindrical steel tank model considering the presence or not of fi xed roof and added mass at the top of the tank for various fl uid levels.
The test results confi rm the occurrence of both beam-type and oval-type vibration modes and show that the larger content of liquid inside the container amplifi ed the acceleration along the height of the cylindrical tank. The oval-type vibration modes are seen to be more dominant in case of large water-to-structure mass ratio.
