Abstract

Finite element model of a 220kV transmission tower was established in general software ANSYS. The constrained method of the freedoms of tower foots with foundation settlements was proposed. According to the monitoring data of the non-uniform settlement, the relative settlement values were applied at the tower foots as displacement loads. By considering the relative position relationship between the wind direction and the settlement direction, the foundation settlement case can be combined with the design wind load case and the design ice load case, and structural analysis of the transmission tower totally includes 32 cases. The stresses of the main members and diagonal members at the tower head and tower body were calculated and assessed for different load cases. Optimization on the angle between staying wire and the ground was carried out. The reducing efficiency of stresses by using staying wires for two angles between the staying wires and the ground was compared.
