The Hysteretic Behavior of Single C-type Cold-formed Cantilevered Member

The flange and web of cold-formed thin-walled steel have small thickness and big width-thickness ratios, its mechanical properties are very different from ordinary steel members. In this paper, we performed three groups of the finite element hysteretic performance analysis of cantilevered member based on the cold-formed thin-walled steel resistance test, the results show: component get bending torsion coupling damage under cyclic loads; Sectional dimensions of members under cyclic loading has a greater impact on the carrying capacity; The batch cold-formed thin-walled steel with good material ductility.
