| Abstract: | In this paper the stiffness matrix of rectangular tube-in-tube element, of which the cross-section has bisymmetric axes, is devoloped. It can be used to simplify analysis of dynamic behaviors of the framed-tube and tube-in-tube structures considerably. Numerical examples show that the method in this paper has the advantages of accuracy and effectiveness. |
