| Abstract: | The local yielding of the tower leg node occurring in the full-scale test of the first SZT2 tubular tower for the 1 000 kV AC double circuits is analyzed and checking calculation is carried out according to the newly-published industrial code Q/GDW 391—2009.A FEA model is established for the failure nodes by the software ANSYS and simulation analysis is carried out,which indicates that the results of theoretical analysis and FEA simulation is in good agreement with the testing results.In the end,several alternative design schemes are compared for the nodes and the optimal model is analyzed by FEA and some suggests are proposed to prevent local yielding. |
