Abstract:With the rapid development of power grid and the continuous improvement of voltage on the transmission tower,the carrying capacity and stability have become increasingly demanding.In this paper,finite element analysis software ANSYS is used to establish two models of transmission tower—rigid frame model and the hybrid model,with the static strength analysis and eigenvalue buckling analysis of two models under various conditions,stability factor of each order component is obtained,which provide a reference for the assessment of the stability when design transmission tower.
Keywords:transmission tower  stability  buckling analysis  rigid frame model  hybrid model
