Evidence from the meteorological community is examined in an attempt to assess the likely forms in which climate change will manifest itself. Particular attention is focussed on the possible extent, intensity and frequency of severe events e.g. hurricanes, heavy rain, prolonged dry spells etc. Ways in which these might be expected to influence our approach to structural design are discussed. Whilst it is not suggested that specific changes are indicated, an approach in which greater attention is paid to the likely manifestation of climate change on a case by case basis is thought to be prudent. Because of the obvious uncertainties of the subject the tone is deliberately one of raising issues. A better understanding of the quantitative effects of climate change on those environmental features that influence structural design is indicated. Prof. D. A.

The structural form of aircraft maintenance hangars is evaluated against the requirements of the next generation of larger aircraft. Initially, trends in passenger growth and aircraft size are reviewed and their impact on hangar requirements assessed. Guidance is then given on those issues that must be addressed in the design and planning of new hangars and the possible upgrade of existing stock. Comparisons are also made between the internal flexibility and structural requirements of a clear width, multi-bay hangar with the benefits provided by including internal columns which reduce the scale of the roof structure, simplify construction and minimise the building volume, thus optimising the operating, environmental control and capital costs.
