| Abstract: | Multi-planar tubular joints applied in practical tower are investigated numerically on the condition of ultimate tension and compress by employing the finite element methods. The distribution of stress and deformation are analyzed, considering the influence of branch tubular lap, stress concentration factor and the ultimate strength of tubular joints. The possibility of adopting concrete-filled steel tubular locally to improve working situation has been proposed. |
