The paper mainly describes the detailed study resulted on bending carrying capacity of two kinds of cold-formedsteel beam with abroach and asymmetric section. This paper has completed 9 groups tests of torsion bending, and totally 12 specimen based on the current theory, deducing the critical moment of asymmetric section under lateral loading, providing the formula of coefficient of integral stability, and compared with tests results determined the simplified formula for engineering design.
