...M. Utsumi; K. Ishida The radial second mode of sloshing in a circular cylindrical oil storage tank induces an out-of-plane deformation of the floating roof deck. The radial contraction of the deck due to this out-of-plane deformation contains modal components with circumferential wave numbers 0...

...M. Utsumi This paper investigates the use of dynamic vibration absorbers as a means to reduce the vibration of a floating roof due to sloshing caused by long-period earthquakes. It is shown that the damping ratio of the primary system caused by the dynamic vibration absorbers increases with rising...

...M. Utsumi; K. Ishida In a previous paper, a cost-efficient modal analysis method for the vibration of a floating roof coupled with nonlinear sloshing in a circular cylindrical oil storage tank is presented. This method is extended to the case in which the out-of-plane deformation of the roof-deck...

...Tetsuya Matsui; Yasushi Uematsu; Koji Kondo; Takuo Wakasa; Takashi Nagaya The dynamic response of a floating roof in a cylindrical liquid storage tank under wind loads is investigated analytically. Wind tunnel test in a turbulent flow is carried out to measure the wind pressure distributing over...

...Tetsuya Matsui An analytical solution is presented to predict the sloshing response of a cylindrical liquid storage tank with a floating roof under seismic excitation. The contained liquid is assumed to be inviscid, incompressible, and irrotational, while the floating roof is idealized...

...Xiushan Sun; Yinghua Liu; Zhangzhi Cen; Shutian Lin In this paper, the strength and buoyancy problems of the floating roof with continuous beams and dome frames are analyzed by the finite element method (FEM) and model experiment method. The modified-loading method with relationship between...
