While Design a tall vertical column i have come through that the when a reinforcing plate is added to the trunion pipe PV-elite doesnot calculate the stress considering the combine thk of shell + pad.(for an ez Shell thk -10mm & pad thk -12mm & combine thk = 22mm. Without this combination it would be assume all of the trunnion stresses are directed solely to the shell or plate, which contradicts the purpose of the plate. Reinforcing plates are not designed to transfer the lifting loads from the trunnion to the shell, but that the trunnion barrel should be directly attached to the shell for this purpose.

My query is what is the Basis of WRC PV-elite is talking if its not considering as per above statement.
