    hi, in the "egg box" section of ISO 12125-6 they tell us what unsupported lengths / spans to use in the stiffener calculation of 12215-5, but they also give a new design pressure to use:

    "The design pressure shall be obtained using a design area, AD, based on the stiffener spacing and 60 % of the grid dimension."

    does anyone understand this?
