For field interpretation of Plastic Section, the issue is cross-section classification. What should be selected? Avoid the common trap that classification is unrelated to width-thickness ratio.
Choose the correct answer
plastic sections are never compact
a plastic section can develop and sustain plastic moment with rotation capacity
classification is unrelated to width-thickness ratio
