Discussion on The Fabrication of a 90-ton Welded Crane Girder By E. Ibbotson, M.I.Struct.E., and and

The PRESIDENT, introducing the authors of the papers, recalled that the Civil Engineering Department of Leeds University, under the direction of Professor R. H. Evans, had collaborated for many years with the late Mr. P. Mitchell, of Messrs. Dorman Long & Co., Ltd., on an extensive investigation concerning the stress distribution in a large welded girder, and the papers to be presented that evening were the outcome of that work. Mr. Mitchell had died early in 1949, and Mr. Ibbotson,
who had been working with him, had continued the preparation of the paper.
