Inglis A : A Fully Rigid Multi-Storey Welded Steel Frame. Discussion on the paper by J. Heyman MA PhD CEng MICE. J. C. H. Finlinson BSc CEng MIStructE MICE and R. P. Johnson MA CEng AMlStructE AMICE

Two sorts of figures are referred to in this text : those appearing in the original paper and those produced in the course of the discussion. The latter are distinguished by the prefix D. Professor M. R. Horne: ‘The authors have given a clear and concise description of their method of design. They have partly achieved this by omitting all the preliminary procedures which must have been necessary, since trial and error calculations feature strongly in the method of designing the columns. The trial and error process is unavoidable in any economic, rational procedure in which elastic continuity and member stability are involved. If the whole gamut of calculations described by the authors for checking the adequacy of their sections is gone through with respect to the first choices of members, unnecessary labour is expended. As in any method of design, short cuts will soon be found after one has understood and become familiar with the steps involved. An examination of the authors’ design calculations has suggested the following approximations to be applied in a preliminary design.'
