Continuous-discretization method is used to analyze the dynamic characteristics of high-rise building cylinder structure. The displacement function used in the derivation of the stiffness matrix of the equivalent cylinder inter-layer element can reflect the shear lag effect of the cylinder structure. This equivalent unit of the body and the assumption that the rigid floor and the structural mass are concentrated on the floor make the analysis of dynamic characteristics of the cylinder structure greatly simplified.Compared with the finite element method, it has the advantages of simple calculation and convenient application. , This method has high accuracy and efficiency
