Deflections of pneumatic masts and columns

Résumé

Like all structural elements, inflatable beams can be subjected to combined loads. This may be the case for inflatable masts or inflatable columns supporting floors. This study addresses inflatable beams subjected to combinations of compression and bending. Whereas the mechanics of inflatable beams subjected only to transverse loading is now well established, the study of inflatable beams subjected to combined loads has still received few investigation. Furthermore, whereas the effects of individual loads are superimposed when beams are made of conventional materials such as steel, the problem is more complex for inflatable beams since compressive forces counteract the effects of internal pressure and reduce the stiffness. This study presents new analytical formulas for inflatable beams subjected to bending and compressive loads. Buckling load and wrinkling limit load are also proposed, taking into account the internal pressure.
