| Abstract: | K-node jointed by inserting plate are researched by full-scale model testing research and nonlinear finite element analysis,including three kinds of inserting plate as C-shaped,U-shaped and cross ones.The distribution and changing trends of stress is found out in steel tubular joints;and their reliabilities and safeties used in 1 000 kV Huainan to Shanghai UHV transmission tower are proven.Some suggestions for the use of C-shaped,U-shaped and cross inserting plates in design of steel tubular tower are presented. |
| Keywords: | transmission tower node test C-shaped inserting plate U-shaped inserting plate cross inserting plate |
