The health degree of transmission tower directly affects the security and stability of power system because of its complex operation environment. In this paper, a health degree evaluation method of transmission towers based on Game Theory is proposed by selecting evaluation indexes from the structural performance of transmission towers, and the same time the economic risk of evaluation indexes and the objectivity of failure frequency are considered. The health degree of 220kV transmission tower is analyzed and calculated under strong wind condition, and its health degree is judged to be in normal state. The advantage of this method is that it can comprehensively evaluate the health degree of transmission towers from multiple perspectives.

The bolted connection is prone to slip under external load in the lattice transmission tower, which will affect the internal forces and deformation of tower. In order to better simulate the effect of bolt connection slippage on transmission tower, the load deformation relationship should be established. In this paper, the single lap splice bolt connection under tension load is tested and the load displacement curve is obtained. Furthermore, the existing model of single lap splice bolted connection is modified, which will plays an important role in the influence of the bolt slippage of the transmission lines towers more accurately and reasonably.
