Correspondence on Code Servicing Panel on Rationalisation of y-Factors-Second Report to the Structur

Dr. 0. A. Kerensky (Past President): I consider that the particular case of the Kessock Bridge is almost sub judice since, apart from the historical background supplied by Mr. Clements, we have no details of the original design, nor of the reasons for the very much cheaper alternatives-and there must be some very good reasons for this! But, most important of all, we do not know how the job will turn out and what will be the final cost to all concerned-i.e. to the nation.

The intensity of snow loading and the provisions of CP3: Chapter V have generated a deal of interesting correspondence over the past year. Verulam

Our subject of theory of structures had its origins around the beginning of the 19th century, and centred first upon the tension and compression properties of the structural materials then current, and upon the behaviour of beams. By 1807 Young had published his work on the theory of beams and struts, and by 1822 George Rennie and Tredgold had reported the results of their tests on materials. Thus the engineering science now known as ‘strength of materials’ had emerged. Sir Alfred Pugsley
