The authors conclude that the flexural strength of the welded web beam to square tube column joint is estimated from the equality hypothesis of plastic virtual work for the yield line mechanism. The discussors are of the opinion that the equality hypothesis of plastic virtual work proposed by the authors is not based on the theory of mechanics and the procedure to arrive the solution is incompatible with the limit analysis.
