Abstract

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 the roof surface. The measured data for the wind pressure is then utilized to predict the dynamic response of the floating roof, which is idealized herein as an isotropic elastic plate of uniform stiffness and mass. The dynamic interaction between the liquid and the floating roof is taken into account exactly in numerical sense within the framework of linear potential theory. The numerical results are presented, which illustrate the significant effect of wind loads on the dynamic response of liquid-floating-roof system in a storage tank.
