With the increasing demand for lightweight steel structure, the effectiveness and accuracy of the design is also more and more important. For this reason, the performance of the structure must be well understood. Therefore, the performance of channel members under bidirectional bending is studied. Several simulation methods are proposed to analyze the nonlinearity of channel. Highlighting the link between the normal use limit state and the ultimate bearing capacity state. The economical and effective design of channel steel under the action of bidirectional bending is put forward in order to achieve economic and light effects. Several methods are proposed to solve the design problems commonly encountered in practice. Introduce analysis procedures to steel structure designers that can be used to optimize the channel size for bi-directional buckling.
