【Abstract】 In this paper,the strength, stiffness and buckling of large FRP conducting wind channel in cooling tower are analyzed using orthotropic shell theory. The original scheme of structure is modified and the improved structure is analyzed by finite element method. The result shows that the wind channel with new structure and thickness suggested by this paper is more economical and reasonable.更多还原
