To investigate the compression performance of cold-formed thin-walled steel T-shaped composite edge columns with web stiffeners, axial and eccentric compression tests were conducted on eight groups of specimens. The influence of “V”-shaped longitudinal stiffening ribs on the failure modes and bearing capacity of the components were revealed through finite element model validation and parameter analysis, and an improved calculation method for bearing capacity was proposed. The results indicate that under axial compression, local buckling first appears in the web of the T-shaped composite edge column without stiffening ribs, ultimately leading to overall crushing failure. After adding “V”-shaped stiffening ribs, the stiffness of the single-limb C-shaped steel web is enhanced; the local buckling mode of the T-shaped composite edge column is improved, and the bearing capacity increases by approximately 15%. As the eccentricity increases, the failure modes of the specimens remain similar, and the ultimate bearing capacity shows a decreasing trend. The bearing capacities under axial and eccentric compression predicted by the effective width method are conservative. Both the finite element results and the test results are greater than the calculated results, with the average ratios being 1.238 and 1.143, respectively. After modification, the ratio of the results predicted by the effective width method to the simulated values ranges from 1.000 to 1.074, indicating high prediction accuracy.
