Prestressed membrane structures — The ultimate thin-walled structure
AbstractWhilst for normal thin-gauge materials such as steel and aluminium, buckling is a problem when the ratio of unsupported width to thickness is perhaps in the order of 200 or so, membrane roof structures may behave satisfactorily with ratios of up to 50 000 and thus might be termed the ‘ultimate thin-walled structure’. All modern architectural membrane structures are prestressed to maintain a tensile state and to reduce deflections under applied loadings such as from wind. These forms of ‘soft shells’ are in two broad categories — the air-supported type and the tension type. This paper discusses the general design principles which are used to achieve exciting, visual and technologically intriguing forms with such high slenderness ratios.
