| Abstract: | In accordance with loading features of stay cables, this paper derives computational formula for end bending stress when axial force of stay cables changes. Example analysis proves that the bending stress of stay cables cannot be ignored, and control measures for bending stress of several stay cables commonly used at home and abroad are introduced. |
