Abstract

Abstract

Distortional buckling is one of the most important buckling modes for cold-formed lipped channel sections as well as local buckling and global buckling may change mechanical properties and decrease the ultimate load of members.It was reviewed the researches on distortional buckling and compared the existed design methods according to five national(regional) codes and the latest research achievements.Based on the comparison between five calculated data and test results, it was shown that the direct strength method of North American specification has widespread application and relative high accuracy.
- cold-formed steel,
