Description: The authors thank the discussers for their interest in the paper and for pointing out the error in Equation 5. The discussers compared the bearing capacity factors predicted by different models for a smooth circular footing. However, the comparison indicates that all the methods over-estimate the bearing capacity factor, and the Tresca–Mises method, which includes a greater approximation to the original Tresca plastic potential function, gives a closer prediction to the exact solution. The method proposed by the discussers shows about 7% inaccuracy as compared with the exact solution. It is the view of the authors that this numerical example fails to show how application of a more accurate flow rule in a finite element analyses will result in a better prediction.
