Abstract
Welded built-up square CFT columns are widely employed in construction field thanks to their structural safety because the bent steel plate mitigates stress concentration, improves workability and maximizes the composite effect enabled by the bent ribs. The anchor effect of the ribs in the columns enables more efficient and economic design using thin steel plates when compared with generic square CFT columns. We suggest the advanced method of using steel fibers to improve structural stability and ductility. The main parameters in the experiment are mixing ratio of steel fibers and loading method.
