The Structural Engineer as Arbitrator, Expert Witness and Advocate

The authors, introducing their paper, amplified the methods of construction and showed. a number of slides. (Figs. 1 and 2 below illustrate the state of the building at the time of presentation of the paper when nearing completion, and were among the slides shown.)

The CHAIRMAN, whose pleasurable duty it was to propose formally a vote of thanks to Dr. Meyerhof for his paper, said there was no need to emphasise the importance of the subject discussed therein; its importance was indicated by the large number present at the meeting. In the paper Dr. Meyerhof had given a very nice blend of the theoretical and the practical; in other words, he had given the results of research work and had analysed them, and an indication of their practical application. The meeting wished to thank him heartily for his paper and for his excellent presentation of it.

The “Vierendeel,” or “open-frame,” girder, has been extensively employed on the Continent and elsewhere, mostly in bridge construction. Few continuous girders of this type have been built, but many uses may yet be found for them. A paper recently published in Japan deals with a method of analysis of this highly-redundant continuous structure, and is probably the first in the field. The method propounded there is based on the well-known Slope-Deflection Method, and involves the systematic wriring of a large number of simultaneous equations and their subsequent solution by iteration.
