| Abstract: | In this paper, the finite element method is used for overall stability analysis of tall building tubular structures. The stiffness matrix and geometric stiffness matrix of rectangular tube-in-tube element of which the cross-section has bisymmetric axes are developed. It can be used for overall stability analysis of tall framed-tube and tube-in-tube structure. The accuracy of the method is confirmed by examples. |
