Herringbone column because of reasonable force , save steel , is used in the main substation architecture column form . 500kV overhead column architecture usually rigidly connected with the word column form . This form of connection with a reliable power transmission , processing , easy to install speed advantages , but the structure is more complex , the current lack of a clear calculation. In view of this , we use the finite element analysis method elevated columns and column connection node herringbone analyze the performance of the force , as well as its design method are discussed. Firstly, according to the word viaduct columns and column connections of structural features to establish a node ANSYS finite element model, and two 1:2 scale model test results were compared and analyzed by both the bearing capacity , deformation and strain distribution verified by comparing the finite element model is correct . Then , the paper prototype specimen parameter analysis , the main consideration of the upper and lower column capitals and lower stiffener plate thickness, layout and the use of high-strength steel for the mechanical properties of the node . Finally, according to results of numerical analysis papers given node configuration recommendations , and node design methods are discussed , for practical engineering design .
