The Institution welcomes as President for the Session 1958-1959 Mr. G. S. McDonald, M.I.Struct.E., M.I.C.E., M.I.Mun.E., who takes office on the 2nd October.
A brief introduction states the proportion between structure and total building cost and considers the effect of ancillary buildings on hangar design. A description is then given of aluminium as a structural material followed by a detailed account of the design of a 200 ft. span aluminium hangar. Unusual features of three other types of aluminium hangar are then given. Tubular steel as a structural medium is discussed and illustrated by a description of a 150 ft. two way span tubular steel hangar. Conclusions are stated and a bibliography given.
The structural industry was one of the early users of electric arc welding and there are many examples which date back to the 1920’s. Its use increased steadily until the Second World War, but it was during the war and in this post war period that the greatest increase in its application has taken place. It has now become one of the leading methods of fabrication and welded work, as a percentage of the total structural
production in this country, rivals all other methods. Indeed, in many structural fields, for example rigid frames and structures designed by the plastic theory, it is now the only method of fabrication in use.
