The present paper describes a method for evaluating the collapse load from the tension- and bending-displacement charts. The plastic constraint factor, the collapse load and the 02% proof strength all exceeded the upper bound solution. The two collapse mechanisms observed are tension and bending collapses. Interaction of tension and bending results in a larger collapse load than that obtained from evaluating photo-plastic fringe, especially under simultaneous tension and bending loadings. The maximum load yielded more easily the test collapse load than the two elastic-slope method.
