Safety Assessment of Transmission Towers Based on Entropy Weight-Topsis

In order to solve the problem of low reliability of the weight coefficients of the influencing factors in the existing evaluation method of the transmission tower safety assessment project, an entropy weight method based on the improved entropy weight method is proposed. An evaluation model of transmission tower safety assessment project based on improved reliability entropy weight method is proposed. Using this method, four safety evaluation indexes were established, including the reliability index of the transmission tower, the von Mises stress, the change coefficient of the maximum stress mean and the total displacement strength. By constructing the finite element model of the transmission tower, extracting the values of various safety indicators, and calculating the objective weight of each index and scoring it, an objective safety assessment model was constructed, and the scientific decision-making of the safety assessment project of the transmission tower was realized. The simulation results show that the proposed method can provide theoretical support for the safety assessment engineering of transmission towers.
