The Structural Engineer, Volume 31, Issue 4, 1953
In May, 1950, the Ministry of Civil Aviation invited tenders for the design and construction of a three-bay hangar at London Airport. With a view to reducing maintenance costs to a minimum, the roof structure was to be fabricated in aluminium alloy but the stanchions, at the discretion of the tenderer, could be either steel or aluminium. This paper will demonstrate that aluminium is a material to be seriously considered for work of this nature. L.E. Ward
In presenting a previous paper', the author demonstrated the solution of a five-bay gabled frame of which each bay was unsymmetrical in geometry and loading. The solution was not then published, and in the present paper the calculation is set out in a form which can be applied to gabled frameworks with any inclination of the two rafters and With any loading. If the loading and the bays are symmetrical there is a considerable simplification of the general case. Arthur Bolton
This month's letters include additional references for the June issue's Regent Street disease article and discussions about seismic design and minimum qualifications for carrying out structural engineering services.
