In this paper, the finite element method is applied to the overall stability analysis of high-rise cylindrical structures. The cylinder stiffness matrix and element geometry stiffness matrix in rectangular tube with double symmetry axis are derived. Can be used for the overall stability of the tube and tube in the cylinder structure. The calculation results verify the accuracy of the proposed method.
