To study the wind load shape coefficient of angle steel reinforced transmission towers,the com-monly used forms of angle steel reinforced sections are introduced.In this paper,the Computational Fluid Dy-namics(CFD)method is used to simulate the shape coefficients of various angle steel reinforced sections under two-dimensional flow fields,and the results are compared with the values specified in relevant codes.The calcu-lation method of shape coefficients based on member loads in the Japanese JEC standard is also discussed in de-tail.Using an angle steel reinforced transmission tower section as a case study,the shape coefficients of various reinforced section forms are calculated using both the JEC empirical formula and numerical simulation methods.The results are then compared with the shape coefficient of the unreinforced tower section.The results indicated that,compared to the shape coefficient of the angle steel towers,the shape coefficient of the box-shaped rein-forced tower section increased by 1％,while the shape coefficients of the other angle reinforced tower section decreased by 2％to 18％.Additionally,the shape coefficient calculated using the JEC empirical formula is 2％to 15％higher than that obtained from the numerical simulation method.This study provides references for the wind load calculation of angle steel reinforced transmission towers.
