抄録
A computational method based on coupled FE (finite element) and analytical solutions is proposed for predicting the sloshing response of a floating roof in a cylindrical liquid storage tank subjected to seismic excitation. The liquid is assumed to be inviscid, incompressible and irrotational, while the floating roof is considered as an orthotropic elastic plate of arbitrary axisymmetric form. The method of solution is based on applying the FEM to evaluate the free vibration modes of the floating roof in air into which the response of the floating roof is expanded. The liquid-floating roof coupling analysis is then performed semi-analytically based on linear potential theory. The method is easier to apply and computationally more efficient than the conventional 3-D analysis based on FE modeling for both the floating roof and the liquid. Numerical results are presented to illustrate the applicability of the proposed method and to investigate the effect of rib-stiffening on the sloshing response of rib-stiffened floating roofs.
