AD.2007-03.2.7 Eurocode 3 Updated to Support Design of Slender Box Sections

Both the ENV and DD versions of Eurocode 3 steel design need to design box sections that have slender elements.

Members that are specified with steel hollow box section properties that contain slender elements can now be designed to Eurocode 3. Previously, these members would not be designed and result in a warning in the output stipulating that slender members are limited to I section properties only.
