Cold-formed steel channel struts are used in the fabrication of double-layer grid-space frames. The study is reported of the behavior of eccentrically loaded, cold formed steel, lipped-channel compression members through postbuckling behavior. Experimental details are described. The results show that there is good agreement between theory and experiments. There was fair agreement for lateral displacements in the prebuckling regime. The peak loads are given by the secant formula for negative eccentricities between the shear center and close to the centroid. For small negative eccentricities close to the centroid and for postive eccentricities, the torsional-flexural load controls. The study results are discussed in detail.
