Problem:
How Autopipe calculate the Forces and Moments to evaluate the "DNV local buckling category"?
Solution:
Force and Moment components for Functional, Environmental, Interference and accidental categories are considered as per selections made on DNV Result Options dialog:
Forces and Moments components defined for corresponding categories are then used to calculate design load effects as per DNV code’s equation 4.6/4.8:
These components are then used by AutoPIPE to calculate “internal overpressure” (code’s equation 5.19) and “external overpressure” (code’s equation 5.28), as per applicable conditions for DNV local buckling category.
