By 2001, the COFS had completed four standards for cold-formed steel framing on. More energy dissipation comes at the cost of less cumulative axial deformation before tensile rupture. recruited active members and initiated standards development projects. However, one remaining barrier is the lack of hybrid construction details giving builders the option of using steel or wood as appropriate. The total hysteretic energy dissipated within the damaged half-wave decreased with increasing cross-section slenderness. organizations have addressed several barriers to the widespread use of cold-formed steel framing. Damage accumulated within one half-wave after buckling. Cyclic response showed large post-buckling deformations, pinching, strength and stiffness degradation. The cyclic loading protocol was adapted from FEMA 461 with target displacements based on elastic buckling properties. Specimen cross-section dimensions and lengths were selected to isolate specific buckling modes (i.e., local, distortional or global buckling). Fully characterized cyclic axial load–deformation response of individual members is necessary to facilitate performance-based design of cold-formed steel building systems. The organizations and the Committees have made a diligent effort to present accurate, reliable, and useful information on cold-formed steel design. This paper summarizes results from an experimental program that investigated the cyclic axial behavior and energy dissipation of cold-formed steel C-sections structural framing members. Committee on Cold Formed Steel Structural Members (S136), and Camara Nacional de la Industria del Hierro y del Acero (CANACERO) in Mexico.
