Regarding the reinforcement calculation for openings per GB/T 150: For a single opening: For multiple openings: ———————————————————————— Question: When the distance between the centers of two openings is less than the sum of their diameters, but their reinforcement areas do not overlap each other； That is, how should the calculation be carried out, between single-hole and multi-hole reinforcement calculations? Single hole or combined?

When the reinforcement areas B of the two do not overlap, it can be calculated as a single hole

Thank you. Referencing ASME Code Section 8-1, Volume UG-42(a), also uses the reinforcement area as the basis for determination.
