Abstract:In order to get the optimal solution under different structural forms of a 750kV combined framework, SAP2000 software was used to conduct the finite element analysis on pure steel pipe herringbone column structure, concrete-filled steel pipe herringbone column structure and tower structure, and the preliminary design was carried out on the section size. Its economy was analyzed. The results show that the tower structure is the optimal solution and has certain economic benefits under the premise of satisfying the bearing capacity and displacement requirements.

Keywords:750kV combined framework; finite element analysis; pure steel pipe structure; concrete-filled steel tube structure; tower structure
