Guy ropes are a structural bearing element that is widely used in mast structures. The task of this element is to ensure the overall stability of the main element - the mast due to the perception of horizontal loads, reducing its estimated length, and ensuring the required deformability of mast structures. An assessment of the values of the reserve coefficients of cable ties of mast structures of energy facilities using the reliability index revealed a significant and possibly excessive safety margin for the ties, when calculating them in accordance with modern building regulations. In this article, the form of the methodology for assessing the bearing capacity of cable ties for cable ties of mast structures is considered. Based on the analysis and calculation, it was concluded that the use of the reserve coefficient to assess the condition of cable ties of mast structures significantly simplifies the assessment of their reliability and defects during operation. The values of the reserve coefficients of cable ties of mast structures for the values of forces from standard loads using the safety index known in reliability theory, depending on the planned service life of the structures, are determined.

摘要

Guy ropes are a structural bearing element that is widely used in mast structures. The task of this element is to ensure the overall stability of the main element - the mast due to the perception of horizontal loads, reducing its estimated length, and ensuring the required deformability of mast structures. An assessment of the values of the reserve coefficients of cable ties of mast structures of energy facilities using the reliability index revealed a significant and possibly excessive safety margin for the ties, when calculating them in accordance with modern building regulations. In this article, the form of the methodology for assessing the bearing capacity of cable ties for cable ties of mast structures is considered. Based on the analysis and calculation, it was concluded that the use of the reserve coefficient to assess the condition of cable ties of mast structures significantly simplifies the assessment of their reliability and defects during operation. The values of the reserve coefficients of cable ties of mast structures for the values of forces from standard loads using the safety index known in reliability theory, depending on the planned service life of the structures, are determined.
