Bolt design

For large-diameter bolts in high-voltage equipment, since strength calculations are not considered, what measures can be taken in the design to ensure they do not fail?

Maybe there really is such a way, it’s just that I haven’t encountered it yet. The large-diameter bolts mentioned by the poster are likely those used on manholes; such bolts require high standards regarding the material used, and it is necessary to test various mechanical properties of that material. Either do not perform any calculations, or refer to existing manholes with the same or similar diameter and scale them according to a certain ratio.
Calculate it. According to the flange design, the strength of the bolts is one of the key factors
Strength calculation is the most fundamental and common design method. In addition, there are also verification experiments, comparative empirical design, finite element analysis, etc. For devices involving strength calculations, it is standard practice to use the aforementioned design methods for individual components.
