Plastic mechanisms of thin-walled cold-formed steel members in eccentric compression

摘要

The paper investigates the possibility to use the local plastic mechanisms to characterise the ultimate strength of short thin-walled cold-formed steel members subjected to eccentric compression about the minor axis. The research is based on previous studies and some new investigations of the authors. The plastic mechanisms for lipped channel members in eccentric compression about minor axis and the evolution of those mechanisms are analysed. Five different types of mechanisms for members in compression with different eccentricities are examined.
