Abstract
Various methods of analysis have been employed to predict the structural behaviour of the Triangularly Folded Plate Barrel Vault, with conflicting results. A review of past analytical and experimental investigations carried out on the structure show that theoretical analysis based on a smaller effective width rather than the overall plate width is capable of closely predicting the deflection behaviour of the structure. This paper presents an experimental study of the behaviour of a triangularly folded plate barrel vault with physically reduced plate width. It is found that physical reduction of the plate width to correspond to ‘theoretical’ effective width weakens the structure, by making it less stiff and highly susceptible to buckling at high loads. The results also confirm earlier postulates that the central part of a plate serves to stabilize the folds and helps to prevent torsional buckling at higher loads. The results are useful when considering the design and construction of cost-effective triangularly folded plate structures.
